Evaluation of the healing process in fractures using early and delayed bone scanning.

Fifty-two fracture sites were evaluated by bone scintigraphy after acquiring similar views of the lesions at 4 and 24 h following technetium-99m methylene diphosphonate administration. After calculating 24/4 h radio-uptake ratio (RUR) and using 1.15 as the critical point of separation, fresh healing lesions could be separated from old healed fractures persisting as 'hot spots' with a sensitivity of 100% and specificity of 82%. The 24/4 h RUR technique is a new approach in measuring the osteoblastic activity at the lesion site. The technique appears to have clinical significance in the detection and follow up of the healing status of occult fractures where radiological procedures are of limited value.

Hyperthyroidism caused by a toxic intrathoracic goiter with a normal-sized cervical thyroid gland.

The rare presentation of hyperthyroidism caused by an intrathoracic goiter with a normal-sized cervical thyroid gland is described. The toxic intrathoracic goiter demonstrated avid uptake of [131I] and [99mTc]pertechnetate, with comparatively faint isotopic accumulation seen in the cervical thyroid. A chest roentgenogram and radioisotope scan should be mandatory in cases of hyperthyroidism having no cervical thyroid enlargement to explore the possibility of a toxic intrathoracic goiter.

Computer-assisted radionuclide perfusion study in solitary cold thyroid nodules for diagnosis of malignancy.

A computer-assisted radionuclide perfusion study was performed in 25 cases of solitary 'cold' thyroid nodules to assess their vascularity relative to that of normal adjoining thyroid tissue. Hypervascularity was seen in 3 malignant nodules; 1 follicular adenoma also showed increased vascularity. The 21 nodules demonstrating equal vascularity or avascularity with respect to normal thyroid tissue were benign in nature. Computer-generated time-activity curves were helpful in distinguishing hypervascular from equally vascular nodules. This technique, in conjunction with clinical evaluation, can be of value in deciding whether patients should undergo surgery or receive conservative management.
