There are only a few studies on calf muscle strength in patients with Achilles tendon disorders. Calf muscle strength has been measured after rehabilitation in pa- tients with surgically treated complete Achilles tendon ruptures4,14,15,17 and in patients with complete Achilles tendon ruptures treated either surgically or nonsurgi- cally. 7,18 We have recently, in two prospective studies on middle-aged recreational athletes with chronic Achilles tendinitis/tendinosis, reported the results of surgical treatment followed by 6 weeks of immobilization and of surgical treatment followed by 2 weeks of immobiliza- tion. 1,2 The results showed that it took a long time to recover concentric and eccentric calf muscle strength, de- spite a controlled postoperative rehabilitation including eccentric calf muscle training.

Common Indications The purpose of this guideline is to assist nuclear medicine practitioners in recommending performing interpreting and reporting the results of bone scintigraphy. II. Background Information and Definitions A. Bone scintigraphy is a diagnostic study used to evaluate the distribution of active bone formation in the body. B. Whole-body bone scintigraphy produces planar images of the skeleton including anterior and posterior views of the axial skeleton. Anterior and or posterior views of the appendicular skeleton also are obtained. Additional views are obtained as needed. C. Limited bone scintigraphy records images of only a portion of the skeleton. D. Bone single-photon emission computed tomography SPECT produces a tomographic image of a portion of the skeleton. E. Multiphase bone scintigraphy usually includes blood flow images immediate images and delayed images. The blood flow images are a dynamic sequence of planar images of the area of greatest interest obtained as the tracer is injected. The immediate blood pool or soft tissue phase images include 1 or more static planar images of the areas of interest obtained immediately after the flow portion of the study and completed within 10 min after injection of the tracer. Delayed images may be limited to the areas of interest or may include the whole body may be planar or tomographic and are usually acquired 2-5 h after .
