It is thought that a large amount of albumin leaking from the glomerulus in nephrotic syndrome (NS) is reabsorbed at the proximal tubule and catabolized. Therefore, it is possible the final quantity of urinary protein does not always reflect the amount of leakage of protein from the glomerulus. We experienced two cases without nephrotic range proteinuria thought to involve hypoproteinemia due t...

UNLABELLED Breast and endometrial cancers are the most common invasive malignancies in women, with more than 217,000 new diagnoses per year in the United States. These cancers are often classified into 2 subtypes based on the expression of the classical estrogen receptor. In this study, we describe a new structural class of neutral tridentate 99mTc(I)-estradiol-pyridin-2-yl hydrazine derivative...

We reviewed all patients with a clinically infected foot ulcer attending a specialised neuropathic foot clinic. Neuropathy was confirmed by the inability to feel a 5.07 Semmes-Weinstein hair, areflexia and impaired vibration sense, as measured by a biothesiometer. Of 40 patients who attended the clinic over a two-year period, six with ischaemic ulcers were excluded. The remaining 34 had plain r...

Skeletal metastases are clinically significant because of associated symptoms, complications such as pathological fractures and their profound significance for staging treatment and prognosis. Detection of bone metastatic lesions allows radiation therapy or surgical interventions to prevent pathological fractures from disabling the patients. High sensitivity of bone scanning in determining the ...

Integrin αvβ3 is a molecular marker for the estimation of tumor angiogenesis and is an imaging target for radiolabeled Arg-Gly-Asp (RGD) peptides. In this study, the authors investigated the clinical efficacy and safety of a novel radiolabeled RGD peptide, 99mTc-IDA-D-[c(RGDfK)]2, for the imaging of integrin αvβ3 expression, as a measure of tumor angiogenesis in lung cancers and brain tumors. F...

PURPOSE The differentiation of oncocytoma from renal cell carcinoma (RCC) remains a challenge with currently available cross-sectional imaging techniques. As a result, a large number of patients harboring a benign oncocytoma undergo unnecessary surgical resection. In this study, we explored the utility of 99mTc-MIBI SPECT/CT for the differentiation of these tumors based on the hypothesis that t...

CONTEXT AND OBJECTIVE Studies using radionuclides are the most appropriate method for estimating renal function. Dimercaptosuccinic acid chelate labeled with technetium-99m (99mTc-DMSA) is the radiopharmaceutical of choice for high-resolution imaging of the renal cortex and estimation of the functional renal mass. The aim of this study was to evaluate a simplified method for determining the abs...

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...

UNLABELLED 99mTc-ethylcysteinate dimer (99mTc-ECD) SPECT imaging reportedly fails to show reflow hyperemia in patients with subacute stroke. This study attempts to determine the clinical usefulness of dynamic 99mTc-ECD SPECT in evaluating regional blood flow in subacute cerebral infarction and the kinetic behavior of 99mTc-ECD in infarct areas. METHODS 133Xe and consecutive dynamic and static...
