Imaging evaluation of patients with soft tissue sarcoma.

Imaging provides the clinician with crucial information in the diagnosis, staging, treatment planning, treatment evaluation, and post-treatment assessment of patients with soft tissue sarcoma. MRI, including contrast-enhanced sequences, usually is preferred for evaluating the primary site in extremity sarcomas and lesions of the head and neck. CT generally is preferred for imaging of the chest, abdomen, and pelvis, either in the evaluation of the primary site in those regions or for identifying metastatic disease.

Body surface area and body weight predict total liver volume in Western adults.

Computed tomography (CT) is used increasingly to measure liver volume in patients undergoing evaluation for transplantation or resection. This study is designed to determine a formula predicting total liver volume (TLV) based on body surface area (BSA) or body weight in Western adults. TLV was measured in 292 patients from four Western centers.
