How useful is ultrasonography in suspected acute osteomyelitis?

Sonographically detected subperiosteal fluid and periosteal irregularity have recently been proposed as diagnostic features of osteomyelitis. The purpose of this study was to determine the diagnostic accuracy of ultrasonography for suspected osteomyelitis. Nineteen patients were investigated prospectively with high-resolution ultrasonography for the presence of subperiosteal fluid or cortical irregularity.

The role of high dose 67-gallium scintigraphy in staging untreated patients with lymphoma.

Background: Gallium-67 (67Ga) scintigraphy has been reported to be of limited value in staging lymphoma patients. However, recent technical advances in radionuclide imaging have potentially enhanced the usefulness of this method.

Aims: The purposes of this study were to determine the current: (1) sensitivity and specificity and (2) impact on clinicians' treatment decisions of 67Ga scans performed at a teaching hospital.

The significance of isolated gallium-67 uptake in the hilar lymph nodes of an untreated lymphoma patient.

A 69-year-old woman presented with non-Hodgkin's lymphoma of the right ilioinguinal region in whom bilateral uptake of Ga-67 in hilar lymph nodes was noted on thoracic SPECT. There were no Ga-67 abnormalities elsewhere within the thorax, and a chest CT scan was also normal. The patient received radiotherapy to the inguinal region and remained in clinical remission for 28 months following treatment.

A case of metastatic malignancy masquerading as a hepatic hemangioma on labeled red blood cell scintigraphy.

A 36-yr-old woman with a past history of gastric neuro-endocrine carcinoma (carcinoid tumor) underwent 99mTc-red blood cell (RBC) scintigraphy for evaluation of a 2-cm echogenic liver mass demonstrated on ultrasound. Scan findings were typical of a cavernous hemangioma. On follow-up, however, there was progressive lesion enlargement; histopathology of the resected mass revealed neuro-endocrine carcinoma.
