PURPOSE We performed technetium-99m hexakis-2-methoxyisobutylisonitrile (Tc-99m MIBI) single photon emission computed tomography (SPECT) in 23 patients with primary lung cancer between July 1993 and March 1996. We evaluated the relationships among the uptake ratio, retention index and the prognosis after radiation therapy and/or chemotherapy. MATERIALS AND METHODS Tc-99m MIBI SPECT was perfor...

Technetium-99m dimercaptosuccinic acid (DMSA) scan was performed on a 32-year-old woman with 
 abdominal pain. A normal functioning slightly ptotic right kidney seen planar images. There no activity in the left renal region and small fusiform pelvic area. Pelvic computed tomography (CT) axial images revealed pre-vesical abscess pushing bladder posteriorly to side. On obtained after percuta...

UNLABELLED Assessment of tumor viability and necrosis of non-small cell lung cancer and detection of distant metastases are important for diagnosis, staging, monitoring the response to treatment and planning long-term management. We performed scintigraphy on patients with non-small cell lung cancer to determine the utility of three tumor targeting tracers for diagnosing primary lung cancer, for...

Several radionuclides in a variety of chemical forms have been used for spleen scanning (1). None of these has as desirable physical properties as tech netium-99m, namely, the clean 140 keV gamma, absence of particulate radiation, and short physical half-life (2). As a result, it would be desirable to find a com pound of “9―Tc that could be used for spleen scanning. Technetium-99m sulfur co...

BACKGROUND Technetium-99m sestamibi scintigraphy has become one of the most popular techniques for localization of the parathyroid gland after failure of primary neck exploration. OBJECTIVE To examine the efficacy of sestamibi with the hand-held gamma ray detecting probe for the identification of parathyroid adenomas during revision parathyroidectomy. METHODS We reviewed six cases of probe-...

The use of technetium-99m 2-methoxyisobutyl isonitrile ((99m)Tc MIBI) for assistance in minimally invasive radioguided surgery (MIRS) is growing in popularity as a safe, effective, and proficient technique used for parathyroidectomy in primary hyperparathyroidism (PHPT) treatment. Previously, the preferred treatment for PHPT was bilateral neck exploration (BNE), a very invasive, costly, and len...

Uptake of technetium-99m methylene diphosphonate by the rectus abdominis muscle was unexpectedly found in a 29 year old man who had started to perform 30 to 40 sit ups a day for five days before the bone scan. After a week of rest, serum creatine kinase activity was still abnormal but muscle uptake of technetium-99m methylene diphosphonate had ceased. This specific muscle injury after short ter...

Extramedullary pulmonary hematopoiesis is a rare entity with a limited number of case reports in the available literature only. We report the case of a 66-year-old man with known primary myelofibrosis, in whom a Technetium-99m sulfur colloid bone marrow scan with single-photon emission computed tomography (SPECT)/CT revealed a pulmonary hematopoiesis as the cause of pulmonary hypertension and s...

Cervical spinal Ewing's sarcomas are rare and cause problems in diagnosis. We present an unusual case of a primary extraosseous Ewing's sarcoma arising from the spinal cord. An 18-year-old woman with fever, headache and back pain lasting one month was admitted to the hospital. Whole body bone scintigraphy was performed with 1110 MBq technetium-99m methylenediphosphonate. Scintigraphy clearly sh...
