These patients underwent elective diagnostic coronary angiography within 1 year of attending outpatient appointments, scheduled coronary computed tomography angiogram scans, or computed tomography scans within 1 year of scheduled blood draws.
Because of their concerns about the fetus's exposure to radiation, they avoided the most sensitive test for this potentially life-threatening condition, a CT angiogram — a scan in which injected contrast material makes the blood vessels and obstructing clots easily visible.
Baseline evaluations included: patient history, physical examination, chest X-rays, complete blood count with differential and platelet count, blood chemistry (AST, ALT, sALP, gamma-GT, bilirubin (direct/indirect), protein, creatinine, BUN, uric acid, glucose, Na+, K+, Ca2+, P−), ECG, and echocardiography or multigated angiogram (MUGA) scan with LVEF measurement.
After acquiring the angiogram, line scans were performed along vessels (arteries, capillaries, and veins) at various depths.
Extensive evaluation including ultrasound, CT scan, angiogram and i.v. pyelogram did not reveal any renal or adrenal abnormalities.
A total of 205 CT scan angiograms were reviewed by the independent radiologist.
All stroke patients arriving at our hospital undergo an emergent brain CT scan, CT angiogram (CTA), and CT perfusion (CTP), according to a protocol agreed upon by neurologists and intensivists.
Metformin is recommended to be temporarily discontinued before any radiographic study involving iodinated contrast agents, (such as a contrast-enhanced CT scan or angiogram), as the contrast dye may temporarily impair kidney function, indirectly leading to lactic acidosis by causing retention of metformin in the body.
(1) Pulmonary emboli: clinical diagnosis supported by ventilation/perfusion lung scan, pulmonary angiogram or venous studies.
Baseline imaging (CT or magnetic resonance imaging), hepatic angiogram, and 99mTc-MAA scan (injected into the hepatic artery that was the planned treatment vessel) were performed within 28 days of study entry.
