How Is Carotid Scan Without Infarction Administered
When the blood supply of a tissue is compromised by whatever mechanism, the tissue will stop working and if blood flow is not restored, the tissue will eventually die ("infarct", both verb and noun). The clinical picture that runs with development of an infarct ("heart attack"; ...Read more
Carotid ultrasound: Carotid ultrasound is performed using a gel on the skin and by applying a probe to the neck adjacent to the carotid arteries. The probe uses sound waves to measure the width of the vessel, the velocity of blood flow, and other variables. ...Read more
If brain mr/mra with/without contrast detects 2 mm pca infundibula, can it also detect 2 to 3 mm brain arterial aneurysm if there is one in same study
It should.: If the study has enough fine (spatial) resolution to see the infundibulum then it should be able to see an aneurysm. Should is the key word. There are many reasons on MRI that something may or may not be seen and the arteriogram (angiogram) is the real final diagnostic study. ...Read more
How reliable is a Cardiac CT for calcium scoring in determining whether someone has coronary artery disease or not? Thanks.
Well...: It is reliable, and it does NOT replace a stress test or if needed and angiogram... At your age coronaries should not have much calcium, and yet plaques unless they have calcium would not show. Your symptoms may not be cardiac but rather coming from the lungs... Seek medical attention soon!!! ...Read more
Can an MRI scan "without contrast material" detect accurately an aortic aneurism?If it cannot, why?What are the side effects&harm caused by this MRI?
Invasive examination: A renal angiogram is a minimally invasive examination. The doctor will likely enter the artery located in the right groin initially with a small needle and then change that for a plastic tube. A catheter (small plastic tube) is then advanced into the aorta and then selectively into the renal artery. A small amount of dye is then injected. Us, ct or MRI usually done before this test. ...Read moreSee 1 more doctor answer
Which procedure is more useful to detect artery blockage, angiography, CT angiogram, or cardiac catheterization and why?
Nothing is 100: % diagnostic: why do you ask?Get a more detailed answer ›
Probably: At some hospitals, physicians assistants are who is actually present during the study. As these tests usually involve some type of stressing of the heart, it is important that whoever is supervising the test has the knowledge to make the decision that the patient is stable and that it is safe.. In most cases, a cardiologist has had some input in that decision even if not there for the test. ...Read moreSee 1 more doctor answer
Did carotid ultrasound imaging and came out normal. Possible CABG short term. Is cta of the neck needed, how much radiation it adds or risk.
Ct scan dects brain aneurysms? Is it possible for a CT scan without contrast to reveal an unruptured brain aneurysm? Is the test meant to find that sort of thing?
Is an MRI on the brain withOUT contrast sufficient enough to diagnose major problems? MS, tumour, aneurysm, etc?
Usually, but: Typically, can pick up multiple sizable lesions, but may miss small vascular anomalies or small inflammatory lesions. Usually most significant issues such as tumors are readily visualized. ...Read more
Is siemens avanto "MRA with and without contrast SPGR post coil protocol" considered 1.5t or 3.0t mra? Can both detect 1 to 2 mm cerebral aneurysm
Can you tell me how precise is a nuclear stress ECG at detecting narrowing of the coronary arteries?
Usually accurate: Nuclear stress test using exercise (tread mill or drug induced tachycardia) as well as resting phases for comparison. Test detects ischemic or infarcted heart muscle which can be correlated with coronary artery supplying that portion of cardiac muscle.Test is considered usually quite accurate. ...Read moreSee 3 more doctor answers
