This single breath-hold, non-invasive, and fairly inexpensive CT scan can assess the extent of coronary artery calcium. Calcium scoring can help identifyatherosclerosis(fatty buildup in the wall of the heart arteries). This helps to determine your treatment and risk-reduction plan. ...
It is crucial that people recommended for CT scan with contrast are not suffering from kidney diseases. The contrast agents that are administered either intravenously or orally will be flushed off through the urine, only if the kidneys are working correctly. The iodine contrast can cause serious d...
For example, a CT-scan of the abdomen produces 500 times more radiation than a single chest X-ray and 1,000 times that of a dental X-ray or bone mineral density test. I wonder how many patients would agree to 500 chest X-rays unless they were vitally important?A study in the ...
A heart CT scan generally would be covered by health insurance only if prescribed by a doctor for a patient at risk for coronary artery disease or who has symptoms such as chest pain; but some insurers do not cover the test under any circumstances. Examples include Medicare, which covers hea...

CT Scan Preparation If a patient is going to have a contrast injection, he or she should not have anything to eat or drink for a few hours before the CT scan because the injection may cause stomach upset. To receive the contrast injection, an IV is inserted into the arm just prior to...
Heart Association/American Stroke Association 2018 guidelines set a door-to-imaging time of 25 min as a best practice strategy for the initial management of patients with suspected stroke3. Danish guidelines for patients suspected of SAH recommend a CT scan of the brain within one hour of ...

Dual Source computed tomography – CT scanners with two radiation tubes and detectors each – allows for very high temporal resolution. High temporal resolution and scan speed are important for CT scans of the heart to limit image artifacts from breathing or motion of the heart. This enables...
similar to one for a CT scan. In places where your body has increased metabolic activity, more of the radiotracer is absorbed. The scan picks that up to show areas where something may be wrong, such asheart disease, cancer, or a brain disorder. A PET scan is able to find cellular cha...
