Abstract:
Positron emission tomography (PET)-computed tomography (CT) is a useful device in identifying musculoskeletal lesions that require biopsy. It can be used to localize the primary lesion, identify a site to biopsy, and evaluate metastatic lesions that require follow-up biopsies. Not all malignant tumors have hypermetabolic activity, and there are many benign lesions and physiologic processes that do have increased F-18 fluorodeoxyglucose uptake. Knowledge of these issues is important when reviewing PET-CT and directing subsequent musculoskeletal biopsies.

Description of the Procedures
Computed Tomography (CT) scan:
Computed Tomography (CT) scans use X-ray technology to generate detailed images of bones, organs, and tissues. During the scan, the patient lies on a moving table...
Radiological Investigation III: Pulmonary Angiogram and PET Scan
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
