CT Scan Negligence & Misinterpretation Attorney NY

How CT Scans Work

Computed Tomography (CT) -- sometimes called CAT scan -- uses X-rays and computer processing to create detailed cross-sectional images of the body. A CT scanner rotates around the patient, taking multiple X-ray images from different angles, which a computer combines into cross-sectional "slices" of the body.

CT is the imaging modality of choice for: - Acute stroke: CT is the first-line imaging study for suspected stroke, used to distinguish ischemic stroke (a clot) from hemorrhagic stroke (bleeding). This distinction is critical because the treatment is completely different. - Internal bleeding: CT is highly sensitive for detecting bleeding in the brain, chest, abdomen, and pelvis -- essential for trauma patients and patients with suspected bleeding. - Trauma: CT is the standard imaging study for trauma patients, used to detect fractures, organ damage, and internal bleeding. - Cancer staging: CT is used to detect tumors and determine whether cancer has spread. - Pulmonary embolism: CT angiography (CTA) is the standard for detecting blood clots in the lungs. - Kidney stones: CT is the most sensitive modality for detecting kidney stones.

CT images are interpreted by a radiologist, who issues a radiology report describing the findings and providing a diagnosis or differential diagnosis. In emergency settings, the radiologist may provide a preliminary "wet read" -- an immediate interpretation to guide emergency treatment.

Different types of CT include:

• Non-contrast CT: Used for detecting acute bleeding, fractures, and some tumors.
• CT with contrast: Uses an iodine-based contrast agent to highlight blood vessels, tumors, and organ abnormalities.
• CT angiography (CTA): Images blood vessels to detect aneurysms, stenosis, pulmonary embolism, and other vascular abnormalities.
• CT perfusion: Measures blood flow to the brain, used in stroke evaluation.

Common CT Scan Errors

CT scan errors can occur at several stages:

• Wrong protocol selected: CT protocols are tailored to the clinical question. If the wrong protocol is used (e.g., non-contrast CT when contrast is indicated, or no CT angiography when a pulmonary embolism is suspected), critical findings may be missed.
• Inadequate image quality: If the CT images are blurry, incomplete, or degraded by patient movement or artifacts, the radiologist may miss findings.
• Misinterpretation of findings: The radiologist sees the abnormality but misinterprets it -- for example, calling a hemorrhagic stroke an ischemic stroke, or calling a tumor an infection.
• Failure to detect abnormalities: The radiologist does not see the abnormality at all -- a perceptual error. This is the most common type of radiology error.
• Failure to compare with prior studies: Radiologists often compare current images to prior studies to identify changes. Failure to obtain prior studies can lead to missed new findings.
• Failure to communicate critical findings: The radiologist identifies a critical finding (e.g., a stroke, a bleed, a pulmonary embolism) but fails to communicate it promptly to the treating physician. [Link to: /radiology-errors/communication-failures]
• Contrast-related errors: Failure to screen for contraindications to iodinated contrast (kidney disease, allergy) or failure to administer contrast when indicated.

The Standard of Care for CT Interpretation

The standard of care for a radiologist interpreting a CT scan in New York includes:

- Appropriate qualifications: The radiologist should be qualified to interpret the type of CT being performed. - Proper protocol selection: The correct CT protocol must be selected based on the clinical indication. If contrast is indicated, it should be administered. - Careful image review: The radiologist must carefully review all images using a systematic approach. - Comparison with prior studies: If prior imaging studies are available, they should be obtained and compared. - Accurate interpretation: The radiologist must accurately identify and interpret any abnormalities. - Prompt communication of critical findings: Critical or urgent findings (e.g., stroke, bleed, pulmonary embolism) must be communicated immediately to the treating physician -- often by direct phone call, not just in the written report. [Link to: /radiology-errors/communication-failures] - Clear and accurate reporting: The radiology report must clearly describe the findings, provide a diagnosis or differential diagnosis, and include recommendations for follow-up.

Failure to meet any of these requirements may constitute negligence. Expert testimony from a board-certified radiologist is required to establish the standard of care.

Conditions Missed on CT Scan

CT scan errors most commonly involve missing or misdiagnosing:

• Ischemic stroke: CT is the first-line imaging study for suspected stroke. In the early hours of an ischemic stroke, the CT may appear normal -- but subtle signs (the hyperdense MCA sign, loss of insular ribbon, effacement of sulci) may be detectable. Missing these signs can delay life-saving treatment (tPA or thrombectomy). [Link to: /medical-malpractice/stroke-misdiagnosis]
• Hemorrhagic stroke: CT is highly sensitive for detecting bleeding in the brain. Failure to detect a hemorrhage can delay treatment and lead to permanent brain damage or death.
• Subdural hematoma: A collection of blood between the brain and the skull, often caused by head trauma. Small subdural hematomas can be missed, particularly if the radiologist does not carefully review the images or if the images are of poor quality.
• Epidural hematoma: A rapidly expanding blood collection between the skull and the dura. This is a neurosurgical emergency -- failure to detect and evacuate an epidural hematoma can be fatal.
• Subarachnoid hemorrhage: Bleeding in the space surrounding the brain, often caused by a ruptured aneurysm. CT is highly sensitive for detecting acute subarachnoid hemorrhage, but the sensitivity decreases over time.
• Pulmonary embolism: CT angiography (CTA) is the standard for detecting blood clots in the lungs. Failure to detect a pulmonary embolism can be fatal. [Link to: /misdiagnosis/pulmonary-embolism-misdiagnosis]
• Aortic dissection: A tear in the wall of the aorta. CTA is the standard for detecting aortic dissection, which is a life-threatening emergency.
• Internal bleeding (trauma): CT is the standard for detecting internal bleeding in trauma patients. Failure to detect bleeding can delay life-saving surgery.
• Bowel perforation: CT can detect free air in the abdomen, indicating a bowel perforation. Missing this finding can delay surgery and lead to peritonitis and sepsis.
• Tumors and cancer: CT is used to detect and stage tumors. Missing a tumor on CT can delay diagnosis and treatment, allowing the cancer to progress. [Link to: /medical-malpractice/cancer-misdiagnosis]

CT Scan Misinterpretation and Stroke

Stroke is one of the most time-sensitive conditions in medicine, and CT scan misinterpretation of stroke is one of the most devastating radiology errors. The standard of care for stroke imaging includes:

- Non-contrast CT: The first-line imaging study for suspected stroke. It is used to rule out hemorrhagic stroke (bleeding) before administering tPA (clot-busting medication) for ischemic stroke. Administering tPA to a patient with a hemorrhagic stroke can be fatal. - CT angiography (CTA): Identifies the location of the clot in ischemic stroke, which is essential for determining whether the patient is a candidate for mechanical thrombectomy (clot removal). - CT perfusion: Measures blood flow to the brain, helping to identify tissue that can be saved (the ischemic penumbra) versus tissue that is already dead (the infarct core).

Common CT stroke errors include: - Misidentifying a hemorrhagic stroke as ischemic: This can lead to administration of tPA, which can worsen the bleeding and be fatal. - Misidentifying an ischemic stroke as a hemorrhagic stroke: This can prevent administration of tPA, which could have dissolved the clot and saved brain tissue. - Missing subtle early signs of ischemic stroke: The hyperdense MCA sign (a bright middle cerebral artery indicating a clot), loss of the insular ribbon, and effacement of cortical sulci are subtle early signs of ischemic stroke that a careful radiologist should detect. - Failure to perform CTA: If CTA is not performed, the location of the clot may not be identified, and the patient may not be evaluated for thrombectomy.

Missing or misinterpreting stroke on CT can lead to permanent brain damage, disability, or death. [Link to: /medical-malpractice/stroke-misdiagnosis]

CT Scan Misinterpretation and Internal Bleeding

CT is the standard for detecting internal bleeding, and failure to detect bleeding on CT is a devastating error. Common scenarios include:

- Trauma: In trauma patients, CT is used to detect bleeding in the brain, chest, abdomen, and pelvis. Failure to detect bleeding can delay life-saving surgery and lead to death. - Aortic aneurysm rupture: A ruptured abdominal aortic aneurysm is a surgical emergency. CTA is the standard for diagnosis, and failure to detect the rupture can be fatal. - Gastrointestinal bleeding: CT angiography can detect active gastrointestinal bleeding. Failure to detect the bleeding source can delay treatment. - Intracranial bleeding: Subdural, epidural, and subarachnoid hemorrhages are detectable on CT. Missing these bleeds can delay neurosurgical intervention and lead to permanent brain damage or death. - Post-surgical bleeding: CT can detect post-surgical hematomas and bleeding. Failure to detect post-surgical bleeding can delay re-operation and lead to complications. [Link to: /surgical-errors/post-operative-hemorrhage]

The standard of care requires the radiologist to carefully review all CT images for signs of bleeding, to use appropriate window settings (which can affect the visibility of blood), and to communicate critical findings immediately to the treating physician.

When a CT Scan Error Constitutes Malpractice

A CT scan error constitutes medical malpractice in New York when the radiologist or facility deviated from the accepted standard of care and that deviation caused harm. Key considerations include:

- Was the correct protocol selected? If the clinical indication required a specific protocol (e.g., CTA for suspected pulmonary embolism) and the wrong protocol was used, critical findings may have been missed. - Were the images of adequate quality? If the images were degraded by patient movement, artifacts, or technical errors, the radiologist may have been unable to detect findings -- and the study should have been repeated. - Did the radiologist carefully review all images? Skipping images or reviewing too quickly can lead to missed findings. - Did the radiologist accurately interpret the findings? Misinterpretation -- calling a hemorrhagic stroke ischemic, or calling a tumor an infection -- can have devastating consequences. - Did the radiologist communicate critical findings? Failure to promptly communicate critical findings (e.g., a stroke, a bleed, a pulmonary embolism) 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 CT error. For example, if a stroke was missed and tPA was not administered, the patient may have suffered permanent brain damage that could have been prevented.

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

Proving Your CT Scan Malpractice Case

To prove a CT scan malpractice case, you need:

- Radiology records: The CT images, the radiology report, and any prior imaging studies for comparison. - Medical records: From the treating physicians, documenting the clinical indication for the CT, the treatment decisions based on the radiology report, and the subsequent diagnosis and outcome. - Expert radiology review: An independent review of the CT images by a qualified radiology expert. - Causation evidence: Medical records documenting the harm caused by the delayed or incorrect diagnosis. - Expert testimony: From qualified radiologists and the relevant medical specialists (neurologists, neurosurgeons, trauma surgeons, etc.).

New York Statute of Limitations and Lavern's Law

CT scan malpractice claims 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 CT 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. This is particularly important when a tumor or cancer was missed on CT and not discovered until later.

If the CT 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 CT 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 subtle and difficult to detect.

Defense attorneys use several arguments in CT scan malpractice cases:

• Our Counter: The standard of care requires radiologists to detect findings that a reasonably competent radiologist would detect. We use expert testimony to establish that the finding was detectable -- and that a competent radiologist would have identified it.

Defense: The CT images were technically adequate.

Our Counter: Technical adequacy is necessary but not sufficient. Even with technically adequate images, the radiologist must carefully review all images, compare with prior studies, and accurately interpret the findings.

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

Our Counter: The underlying condition may have contributed to the harm, but the radiology 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]

Defense: The treating physician was responsible for follow-up.

Our Counter: While the treating physician has responsibility for follow-up, the radiologist has a duty to communicate critical findings directly to the treating physician -- particularly in emergency settings where time is critical. [Link to: /radiology-errors/communication-failures]
