Objective- To consider the use of renal scintigraphic evaluation of kidney function in Persian cat and make a comparison between 99mTechnetium ethylenedicysteine and 99mTechnetium diethylenetriaminepentaacetic in renal scintigraphy. Design- Descriptive study Animals- 6 male healthy adult Persian cats - no clinical sign of renal disorders and prior to presentation. Proce...

We present the characteristics of a ventilation-perfusion scan correlating to both planar and single photon emission computed tomography and computed tomography (SPECT/CT) images of the lungs in a patient with SwyerJames (MacLeod) syndrome. A Tc-99m MAA lung perfusion scan was recorded with multiple projections and SPECT/CT. In the ventilation scan, initially dynamic acquisition of aerosol Tc-9...

PURPOSE Imaging with (99m)Tc-sestamibi ((99m)Tc-MIBI) has been used to assess 170-kDa P-glycoprotein (P-gp) expression and predict chemotherapy responses in several types of malignancy, such as breast and lung cancers. The purpose of this study was to evaluate the relationship between (99m)Tc-MIBI accumulation in tumors and sensitivity to chemotherapy in gastric cancer patients. EXPERIMENTAL ...

The authors report a case of alveolar soft-part sarcoma with lung metastases demonstrated by "double imaging" with Tc-99m HDP and Tc-99m MIBI. The tumor originated in the soft tissue with direct invasion to the right scapula, which was hypoactive on bone scan and hyperactive on Tc-99m MIBI images. A focus of dense accumulation of Tc-99m MIBI in the lungs, suggesting metastasis was also demonstr...

Tc-99m-tetrofosmin is an agent to delineate cancer. To elucidate the usefulness of Tc-99m-tetrofosmin scintigraphy, we analyzed the relationship between the uptake of Tc-99m-tetrofosmin and histopathology in patients with lung cancer. SPECT studies were conducted twice: 15 minutes (early scan), and 60 minutes (delayed scan), after intravenous injection of 740 MBq Tc-99m-tetrofosmin. We calculat...

OBJECTIVE Surgical intervention in the form of parathyroidectomy is generally considered only for severe secondary hyperparathyroidism (sHPT). However, correct location of the parathyroid glands before parathyroidectomy is a challenge. The purpose of this study was to compare the diagnostic value of early and delayed phase (99m)Tc-sestamibi SPECT/CT in the detection of parathyroid tissue to gui...

The aim of this study was the investigation of absorbed dose to the kidneys, spleen, and liver during technetium-99 m ethylene dicysteine and technetium-99 m diethylenetriaminepentaacetic acid ((99m)Tc-EC and (99m)Tc-DTPA) kidney scan. Patients who had been prepared for the kidney scan, were divided into two groups (Groups 1 and 2). The first group (Group 1) and the second group (Group 2) recei...

Noninvasive analysis of renal function in conscious mice is necessary to optimize the use of mouse models. In this study, we evaluated whether single photon emission-computed tomography (SPECT) using specific radionuclear tracers can be used to analyze changes in renal proximal tubule functions. The tracers included (99m)TC- dimercaptosuccinic acid ((99m)Tc-DMSA), which is used for cortex imagi...

BACKGROUND: Recently, radiopharmaceutical scanning with Tc-99m-MIBI was reported to depict areas with active bone disease in multiple myeloma (MM) with both high sensitivity and specificity. This observation was explained by the uptake of Tc-99m-MIBI by neoplastic cells. The present investigation evaluates whether Tc-99m-MIBI imaging and magnetic resonance imaging (MRI) perform equally well in ...
