Ct chest gated
WebMar 23, 2024 · In contrast to other CT angiography examinations, cCTA usually requires a rather high flow rate for the contrast media injection, usually between 4-5 mL/sec through an antecubital vein. Beta-blockers and sublingual nitrates are usually administered before the examination to lower the heart rate, avoid arrhythmia and dilate the coronary arteries. WebMar 12, 2024 · Cysts and benign thymic lesions and invasion of mediastinum/chest wall can often be characterized without the use of intravenous gadolinium-based contrast. This is especially important in patients who cannot receive contrast for either CT or MRI (renal failure, history of anaphylaxis to previous contrast medium administration, etc.).
