How Ultrasound Imaging Works

Ultrasound uses high-frequency sound waves (above the range of human hearing) to produce images of the body internal structures. A transducer (probe) emits sound waves that bounce off internal structures and return to the transducer, which converts the echoes into images.

Ultrasound is the imaging modality of choice for: - Pregnancy and fetal monitoring: Ultrasound is the standard for monitoring fetal development, detecting fetal anomalies, and assessing fetal well-being. [Link to: /medical-malpractice/fetal-monitoring-errors] - Vascular diagnosis: Doppler ultrasound is the standard for detecting deep vein thrombosis (DVT), carotid artery stenosis, and other vascular conditions. - Abdominal imaging: Ultrasound is used to evaluate the liver, gallbladder, kidneys, pancreas, and spleen -- particularly for detecting gallstones, kidney stones, and organ enlargement. - Echocardiography: Ultrasound of the heart, used to evaluate heart function, valve function, and structural abnormalities. - Breast imaging: Ultrasound is used to distinguish solid masses from cysts and to guide biopsies. [Link to: /radiology-errors/mammogram-malpractice] - Emergency medicine: Point-of-care ultrasound (POCUS) is increasingly used in emergency departments for rapid assessment of trauma, cardiac arrest, and other emergencies. - Testicular and scrotal imaging: Ultrasound is the standard for evaluating testicular torsion, epididymitis, and other scrotal conditions.

Ultrasound images are interpreted by a radiologist or, in the case of specialized ultrasounds (such as echocardiography or fetal ultrasound), by a specialist with training in that specific type of ultrasound. The interpreter issues a report describing the findings and providing a diagnosis or differential diagnosis.

Common Ultrasound Errors

Ultrasound errors can occur at several stages:

• Improper technique: Ultrasound is highly operator-dependent -- the quality of the images and the ability to detect abnormalities depend on the skill and technique of the sonographer (the technician performing the ultrasound). Poor technique can produce inadequate images that miss critical findings.
• Inadequate image quality: If the ultrasound images are blurry, incomplete, or degraded by artifacts, the interpreter may miss findings. The study should be repeated if the images are inadequate.
• Failure to detect abnormalities: The interpreter does not see the abnormality -- a perceptual error. This is the most common type of ultrasound error.
• Misinterpretation of findings: The interpreter sees the abnormality but misinterprets it -- for example, calling a malignant mass a benign cyst, or calling a DVT something else.
• Failure to use Doppler when indicated: Doppler ultrasound measures blood flow and is essential for detecting vascular conditions like DVT and arterial stenosis. Failure to use Doppler when indicated can miss critical vascular findings.
• Failure to compare with prior studies: Comparison with prior ultrasounds is important for identifying changes, particularly in monitoring fetal growth or tumor size.
• Failure to communicate critical findings: The interpreter identifies a critical finding but fails to communicate it promptly to the referring physician. [Link to: /radiology-errors/communication-failures]
• Wrong protocol or wrong area scanned: If the wrong area is scanned, or the wrong protocol is used, the relevant anatomy may not be evaluated.

The Standard of Care for Ultrasound Interpretation

The standard of care for ultrasound interpretation in New York includes:

- Appropriate qualifications: The interpreter should be qualified to interpret the type of ultrasound being performed. For specialized ultrasounds (fetal, cardiac, vascular), specialized training is required. - Adequate image quality: The ultrasound must be performed by a qualified sonographer using appropriate technique. If the images are inadequate, the study should be repeated. - Careful image review: The interpreter must carefully review all images. - Use of Doppler when indicated: Doppler ultrasound must be used when evaluating vascular conditions. - Comparison with prior studies: When available, prior ultrasounds should be obtained and compared. - Accurate interpretation: The interpreter must accurately identify and interpret any abnormalities. - Clear reporting: The report must clearly describe the findings, provide a diagnosis or differential diagnosis, and include recommendations for follow-up. - Communication of critical findings: Critical findings must be communicated promptly to the referring physician. [Link to: /radiology-errors/communication-failures]

Failure to meet any of these requirements may constitute negligence. Expert testimony from a qualified radiologist or specialist is required to establish the standard of care.

Conditions Missed on Ultrasound

Ultrasound errors most commonly involve missing or misdiagnosing:

• Fetal anomalies: Ultrasound is used to detect fetal anomalies during pregnancy. Missing a serious anomaly -- such as a neural tube defect, heart defect, or chromosomal abnormality -- can deprive parents of the opportunity to make informed decisions about the pregnancy. [Link to: /birth-injury-lawyer] [Link to: /medical-malpractice/fetal-monitoring-errors]
• Fetal distress and growth restriction: Ultrasound is used to monitor fetal growth and well-being. Missing signs of fetal growth restriction or distress can lead to delayed delivery and birth injuries. [Link to: /medical-malpractice/delayed-c-section]
• Deep vein thrombosis (DVT): Doppler ultrasound is the standard for detecting DVT. Missing a DVT can lead to pulmonary embolism, which can be fatal. [Link to: /misdiagnosis/pulmonary-embolism-misdiagnosis]
• Carotid artery stenosis: Doppler ultrasound is used to detect narrowing of the carotid arteries, which can lead to stroke. Missing significant stenosis can delay treatment and lead to stroke. [Link to: /medical-malpractice/stroke-misdiagnosis]
• Abdominal aortic aneurysm (AAA): Ultrasound is the standard for screening and monitoring AAA. Missing a large aneurysm can lead to rupture, which is often fatal.
• Gallstones and cholecystitis: Ultrasound is the standard for detecting gallstones and inflammation of the gallbladder. Missing these findings can delay treatment and lead to complications.
• Kidney stones and obstruction: Ultrasound can detect kidney stones and obstruction of the urinary tract. Missing these findings can delay treatment.
• Testicular torsion: Ultrasound with Doppler is the standard for evaluating testicular torsion (twisting of the testicle), which is a surgical emergency. Missing torsion can lead to loss of the testicle.
• Ectopic pregnancy: Ultrasound is used to detect ectopic pregnancy (pregnancy outside the uterus), which is a life-threatening emergency. Missing an ectopic pregnancy can lead to rupture and fatal bleeding.
• Appendicitis: Ultrasound (particularly in children and pregnant women) can detect appendicitis. Missing appendicitis can lead to rupture and peritonitis. [Link to: /misdiagnosis/appendicitis-misdiagnosis]
• Breast masses: Ultrasound is used to evaluate breast masses, particularly in women with dense breasts. Missing a malignant mass can delay cancer diagnosis. [Link to: /radiology-errors/mammogram-malpractice]
• Cardiac abnormalities (echocardiography): Missing heart valve abnormalities, wall motion abnormalities, or pericardial effusion on echocardiography can delay treatment of serious cardiac conditions.

Fetal Monitoring Ultrasound Errors

Ultrasound is a critical tool in prenatal care, used to monitor fetal development, detect anomalies, and assess fetal well-being. Common fetal ultrasound errors include:

- Missing fetal anomalies: Neural tube defects (spina bifida, anencephaly), heart defects, chromosomal abnormalities (Down syndrome markers), and other structural anomalies can be detected on fetal ultrasound. Missing these anomalies deprives parents of the opportunity to make informed decisions. - Missing fetal growth restriction: Ultrasound is used to monitor fetal growth. Missing growth restriction can lead to stillbirth or other complications. - Missing signs of fetal distress: Biophysical profile (BPP) and non-stress test (NST) are used to assess fetal well-being. Missing signs of distress can delay delivery and lead to birth injuries, including cerebral palsy and HIE. [Link to: /medical-malpractice/fetal-monitoring-errors] [Link to: /medical-malpractice/hie-claims] [Link to: /cerebral-palsy-lawyer/new-york] - Inadequate imaging: If the fetal ultrasound images are of poor quality (due to maternal body habitus, fetal position, or operator technique), critical findings may be missed. The study should be repeated or supplemented with other imaging (MRI) if adequate images cannot be obtained.

Fetal ultrasound errors can have lifelong consequences for the child and family. At MDLaw Firm, we work with maternal-fetal medicine specialists and pediatric radiologists to evaluate these cases. [Link to: /birth-injury-lawyer]

DVT and Vascular Ultrasound Errors

Doppler ultrasound is the standard for detecting deep vein thrombosis (DVT) and other vascular conditions. Common errors include:

- Missing a DVT: DVT is a blood clot in the deep veins, typically of the leg. If undetected, the clot can break off and travel to the lungs, causing a pulmonary embolism -- which can be fatal. [Link to: /misdiagnosis/pulmonary-embolism-misdiagnosis] - Inadequate venous compression: The standard technique for detecting DVT is compression ultrasonography -- pressing the transducer against the vein to see if it collapses. If the sonographer does not adequately compress the vein, a clot may be missed. - Incomplete examination: The standard DVT ultrasound examines the femoral and popliteal veins. If the examination is incomplete (e.g., not examining the entire venous system), clots may be missed. - Missing carotid artery stenosis: Doppler ultrasound is used to detect narrowing of the carotid arteries, which can lead to stroke. Missing significant stenosis can delay treatment and lead to stroke. [Link to: /medical-malpractice/stroke-misdiagnosis] - Missing abdominal aortic aneurysm (AAA): Ultrasound is the standard for screening and monitoring AAA. Missing a large aneurysm can lead to rupture, which is often fatal.

The standard of care for vascular ultrasound requires proper technique (including venous compression for DVT), complete examination of the relevant anatomy, use of Doppler, and accurate interpretation by a qualified interpreter.

When an Ultrasound Error Constitutes Malpractice

An ultrasound error constitutes medical malpractice in New York when the interpreter or facility deviated from the accepted standard of care and that deviation caused harm. Key considerations include:

- Was the ultrasound performed with adequate technique? Ultrasound is highly operator-dependent. If the sonographer used poor technique, critical findings may have been missed. - Were the images of adequate quality? If the images were blurry, incomplete, or degraded, the interpreter may have been unable to detect findings -- and the study should have been repeated. - Was Doppler used when indicated? Doppler is essential for evaluating vascular conditions. Failure to use Doppler when indicated may constitute negligence. - Did the interpreter carefully review all images? Skipping images or reviewing too quickly can lead to missed findings. - Did the interpreter accurately interpret the findings? Misinterpretation -- calling a malignant mass a cyst, or calling a DVT negative -- can have devastating consequences. - Did the interpreter communicate critical findings? Failure to promptly communicate critical findings is a well-recognized cause of harm. [Link to: /radiology-errors/communication-failures] - Did the delay in diagnosis cause harm? The harm must be causally connected to the ultrasound error.

Under New York law, expert testimony is required. A certificate of merit (CPLR 3012-a) must be filed with the lawsuit.

Proving Your Ultrasound Malpractice Case

To prove an ultrasound malpractice case, you need:

- Radiology records: The ultrasound images, the interpreter report, and any prior imaging studies for comparison. - Medical records: From the referring physician and treating physicians, documenting the clinical indication, treatment decisions, and subsequent diagnosis. - Expert review: An independent review of the ultrasound images by a qualified radiologist or specialist. - Causation evidence: Medical records documenting the harm caused by the delayed or incorrect diagnosis. - Expert testimony: From qualified radiologists and the relevant medical specialists.

New York Statute of Limitations

Ultrasound malpractice claims in New York are subject to the 2.5-year statute of limitations for medical malpractice (CPLR 214-a), running from the date of the negligent act (the date the ultrasound was misread).

Lavern's Law may extend this deadline for cancer cases -- giving 2.5 years from the date of discovery, with a 7-year outer limit.

For birth injury cases involving fetal ultrasound errors, the infancy toll (CPLR 208) may extend the deadline -- the statute does not begin to run until the child reaches age 18. However, the infancy toll does not apply to wrongful death claims. [Link to: /birth-injury/statute-of-limitations] [Link to: /cerebral-palsy-lawyer/statute-of-limitations]

If the ultrasound error occurred at a municipal hospital (NYC Health + Hospitals), shorter deadlines apply -- 90 days for the notice of claim and 1 year, 90 days for the lawsuit. [Link to: /hospital-negligence/suing-nyc-h-h]

If the error resulted in death, a wrongful death claim under EPTL 5-4.1 must be filed within 2 years of the date of death. [Link to: /wrongful-death-lawyer]

Common Defense Arguments and How We Counter Them

Defense: The finding was not visible on ultrasound.

Defense attorneys use several arguments in ultrasound malpractice cases:

• Our Counter: We have the ultrasound images independently reviewed by a qualified radiologist or specialist, who can testify that the finding was visible and should have been detected. We also examine whether the correct technique was used, whether Doppler was used when indicated, and whether the images were of adequate quality.

Defense: The patient body habitus limited image quality.

Our Counter: If the patient body habitus (obesity) limited image quality, the standard of care required the sonographer to note this limitation and the interpreter to recommend alternative imaging (CT, MRI) if adequate images could not be obtained. Silently interpreting inadequate images without recommending alternatives may constitute negligence.

Defense: The finding was subtle and difficult to detect.

Our Counter: The standard of care requires detection of findings that a reasonably competent interpreter would detect. Expert testimony establishes that the finding was detectable.

Defense: The patient had underlying conditions that caused the harm.

Our Counter: The underlying condition may have contributed, but the ultrasound error -- the delayed or incorrect diagnosis -- caused or worsened the outcome. Expert testimony establishes that earlier diagnosis and treatment would have changed the outcome. [Link to: /delayed-diagnosis-lawyer/loss-of-chance]
