Will CT scan shows thickening in kidney?

Will CT scan shows thickening in kidney?

Not sure: Ct with and without xray dye is a good test for some kidney problems. Not sure what you mean by thickening. Ct shows kidney stones, masses, kidney size/location ; can give a good idea of whether the kidneys are working well. Ct is also good at showing the site of blockage of urine flow, when present. ...Read more

Would Cardiac stress perfusion scan MRA highlight Pulmonary Hypertension if this was present?

Would Cardiac stress perfusion scan MRA highlight Pulmonary Hypertension if this was present?

Probably not: A cardiac echo/Doppler study would show pulmonary HTN changes by viewing the right ventricular function , size and pressure. There are additonsl studies that can also be done. It is very important to know WHY you have Pulmonary HTN. If due chronic Pulmonary embolism it is a serious situation for which there exists very effective Rx. Other causes can also be treated. Consult your doc. ...Read more

Can a renal ultrasound diagnose renal parenchymal disease?

Can a renal ultrasound diagnose renal parenchymal disease?

Not typically: An ultrasound can suggest radiographic evidence of medical renal disease but cannot diagnose this. To make the diagnosis of renal parenchymal disease the radiographic findings must be combined with blood studies of kidney function and sometimes urine studies for protein or a kidney biopsy. ...Read more

What heart scan is better, CT scanner or ultra scan?

What heart scan is better, CT scanner or ultra scan?

UltraSOUND: I think you mean cardiac ultrasound (also known as echocardiography). They look at different things. Echo sees over all function, wall thickness, chamber dimensions, valves, and can measure blood flow and pressure. Ct is for detecting calcium and looking at the coronary arteries. ...Read more

Is it safe to smoke after a myocardial perfusion scan thallium scan cardiac nuclear imaging?

Is it safe to smoke after a myocardial perfusion scan thallium scan cardiac nuclear imaging?

Well...: Since you had a cardiac nuclear scan, I assume your doctors were looking for coronary artery disease. You seem to be a smoker, which makes artery disease worse. So smoking is not a good thing for you, and you should try to stop. Having said that, you are probably not in any more immediate risk for heart problem for smoking after the nuclear exam. Long term risks are greater with smoking. ...Read more

What is myocardial perfusion scintigraphy?

What is myocardial perfusion scintigraphy?

Let me try to: Myocardial perfusion scan is a nuclear medicine procedure that illustrates the function of the heart muscle (myocardium). It evaluates many heart conditions from coronary artery disease to hypertrophic cardiomyopathy and myocardial wall motion abnormalities. The function of the myocardium is also evaluated by calculating the left ventricular ejection fraction (lvef) of the heart. Good luck. ...Read more

Mibi scan shows diffuse reversible ischemia in keeping with angina?

Mibi scan shows diffuse reversible ischemia in keeping with angina?

Heart disease: Angina means chest pain caused by the heart. This usually comes from clogged arteries. As the arteries initially clog, blood can still get around the blockage and is reversible. This can eventually progress to a worsening blockage where blood can't get around it. This usually results in what is known as a heart attack. Reversible is good but it's important to prevent it from getting worse. ...Read more
