A 73-year-old male was diagnosed with clear-cell renal carcinoma in 2002. He had right nephrectomy, developing thereafter metastases in both adrenal glands and in the right gluteus region. He received immunotherapy and remained with stable diseases until august 2011, when suddenly unfold an unstable condition, developing a renal failure with elevation of creatinine levels and need of dialysis. ...

To compare the myocardial uptake pattern of 99mTc-labeled methoxyisobutyl isonitrile [( 99mTc] MIBI) and 201TI, planar scintigraphy were performed in both patients with documented coronary artery disease and subjects with a low likelihood of disease. Quantitative analysis was employed using a standard interpolative background subtraction algorithm and a new algorithm modified to better accommod...

Markedly elevated111 In labeled leukocyte activity suggestive of acute osteomyelitis was observed in a region of a composite mandibular allograft that was photon deficient on 99mTc MDP bone scintigraphy. This finding was later confirmed by surgical pathology. The patient was treated with intravenous antibiotics and returned two months later with persistent bone infection. The foHow-up thr...

BACKGROUND Nuclear imaging is increasingly being used in the diagnostic work-up of idiopathic inflammatory myopathy (IIM). Increased muscular uptake of technetium-99m-pyrophosphate (99mTc-PYP) has hitherto been assessed qualitatively by planar scintigraphy. We set out to perform quantitative tomographic scintigraphy in IIM. RESULTS Ninety IIM patients and 48 control subjects underwent 99mTc-P...

Ultrasound scanning and 99mTc sulphur colloid scintigraphy are widely used in the diagnosis of the Budd-Chiari syndrome and have been compared at the time of presentation in 18 patients in whom the diagnosis was subsequently confirmed by histology and hepatic venography. Ultrasound was diagnostic in 16 (87%). The findings seen most often included hepatic vein abnormalities, caudate lobe hypertr...

OBJECTIVE Uptake of 99mTc-pertechnetate in salivary glands reflects intact salivary gland parenchyma. However, no standardized protocol for an accurate quantification of parenchymal function has been established so far. METHODS In this paper we report on a validated acquisition protocol supplying a normal database for standardized quantitative salivary gland scintigraphy. RESULTS The major ...

Nontutimorous decrease in 99mTc-GSA accumulation has not been well covered in the literature. Understanding of this phenomenon is, however, essential for accurate evaluation of regional hepatic function. Scintigrams (transaxial SPECT) of 269 patients who underwent 99mTc-GSA liver scintigraphy were reviewed for the presence of nontumorous decreases in 99mTc-GSA accumulation. Nontumorous decrease...
