Imaging quality when using on obese patients or patients with obstructive lung disease.
Stress MPI: gamma rays emitted by patient are picked up by the sodium iodide crystals in the apparatus
CCS: scans patient for calcium and identifies calcium burden based off score
Coronary CTA is used to screen patients with coronary artery disease in a non-invasive way.
Disadvantages of Coronary CTA include use of ionizing radiation, iodinated contrast, and limited use in arrhythmic patients.
What is an adverse effect of cardiac MRI in patients with low creatinine clearance?
Utilizes Gadolinium which can cause adverse skin conditions.
Bleeding Time Anticoagulation Test: When a small slit is made in the skin, the hemostatic mechanisms necessary for coagulation are activated and the time it takes to heal is measured.
Activated Partial Thromboplastin Time: The aPTT measures the time necessary to generate fibrin from initiation of the intrinsic pathway by measuring how long it takes for activating substance, kaolin, to appear
Prothrombin Time: plasma + thromboplastin are incubated and then timed for how long it takes for calcium to appear and indicate the presence fibrin precursor factors.
Thrombin Time: plasma + thrombin incubated and measured for how long it takes fibrin to appear
Fibrin Degradation Products Test: Series of dilutions of serum are texted with FDP-Ab-absorbed latex particles to oberve agglutination
