Computed tomography (CT) perfusion is a new imaging modality that permits the microcirculation of the brain to be evaluated. Unlike conventional CT imaging, which assesses brain structure and morphology, CT perfusion gathers physiologic information about the status of the cerebral perfusion.
What is CT perfusion? CT perfusion is a useful technique for measuring perfusion in the brain. Measuring perfusion may be important for treating stroke, other blood vessel diseases of the brain and brain tumors. CT scanning is painless, noninvasive, and accurate. A major advantage of CT is its ability to image bone, soft tissue, and blood vessels all at the same time.
What is CT perfusion in ischemic stroke? CT perfusion in ischemic stroke. CT perfusion in ischemic stroke has become established in most centers with stroke services as an important adjunct, along with CT angiography (CTA), to conventional unenhanced CT brain imaging. It enables differentiation of salvageable ischemic brain tissue (the penumbra) from irrevocably damaged infarcted brain…
What is CT angiography? CT angiography may provide more precise anatomical details than other angiography exams such as conventional catheter angiography and magnetic resonance imaging (MRI). For CT Angiography, there is no need for sedation or general anesthesia. CT angiography of the heart is a useful way of detecting blocked coronary arteries.
What is the difference between CT perfusion and diffusion magnetic resonance imaging? Whereas diffusion magnetic resonance imaging can identify dead brain tissue, CT perfusion imaging can help identify dying brain tissue—tissue that may recover with prompt and appropriate therapy.

Is CT the better angiogram? “CT angiogram is preferable, as it is a non-invasive test, particularly for patients who are likely to be NOT requiring stents or need to be treated with medications only,” says Asim Cheema, MD, who’s board certified in internal medicine, cardiovascular diseases and interventional cardiology by the American Board of Internal Medicine. Dr.
Why to do CT angiography? Why to do CT Angiography
- Renal function test must be done to ensure normal renal function.
- Ensure no previous history of allergy to contrast.
- Fasting overnight
- Using drugs to lower heart rate prescribed (temporarely) by the cardiologist after consultation including ECG and blood test to assess your renal function and metabolic risk factors: diabetes ,lipid profile
How long does a CT angiogram take? The dye shows up on X-rays. Additionally, how long does a CT coronary angiogram take? The whole procedure, including the preparation, scanning and recovery, can take up to 3–4 hours, particularly if you have been given beta-blockers. The actual CT scanning will take approximately 20 minutes.
What does CT angiogram show? Some reasons to have a CT angiogram include:
- To find an aneurysm (a blood vessel that has become enlarged and may be in danger of rupturing)
- To find blood vessels that have become narrowed by atherosclerosis (fatty material that forms plaques in the walls of arteries)
- To find abnormal blood vessel formations inside your brain
- To identify blood vessels damaged by injury

What is difference between CT scan and MRI scan?
- When compared to a CT scan, MRI produces more detailed images of soft tissues and behind bones.
- CT scan is less expensive and costs half the price of MRI.
- The time required for the procedure depends on whether or not you need a contrast.
What to expect with a CT brain scan?
- fainting
- headache
- seizures, especially if any occurred recently
- sudden behavioral changes or changes in thinking
- hearing loss
- vision loss
- muscle weakness or numbness and tingling
- speech difficulty
- difficulty swallowing
What is a CT scan for stomach cancer? Endoscopy and biopsy are the best methods of identifying stomach cancer. CT scan. A computed tomography (CT) scan can give your doctor detailed pictures of structures inside of the body using X-rays. This test is used after a stomach cancer is diagnosed in order to determine the stage of the cancer.
What is a brain CT imaging perfusion study? Computed tomography (CT) perfusion imaging shows which areas of the brain are adequately supplied or perfused with blood and provides detailed information on delivery of blood or blood flow to the brain. CT perfusion scanning is a noninvasive medical test that helps physicians diagnose and treat medical conditions.
