Her technetium-99m diethylenetriaminepentaacetic acid (99mTc-DTPA) radioaerosol inhalation lung scintigraphy (May 21, 2008) revealed marked hypoventilation of the left lung and retention of the radiotracer in the right peri-hilar region, suggestive of a parenchymal process. The use of 99mTC human albumin macroaggregates (99mTC MAA) revealed no perfusion in the left lung and perfusion defects in...

PURPOSE The etiology of osteonecrosis of the jaw is poorly understood, but preferential mandibular uptake of intravenous bisphosphonates (IVBPs) has been implicated. We examined this association within a prospective study assessing the effect of IVBPs on radionuclide bone scanning. PATIENTS AND METHODS Women with at least 3 osseous breast metastases on bone scanning and previous IVBP use with...

introduction: monoclonal antibodies labeled mainly with 99mtc are being widely used as imaging agents in nuclear medicine. recently pr81 was introduced as a new murine anti-muc1 mab against human breast carcinoma. this antibody reacts with the tandem repeat of 20-mer peptide of protein backbone, and is of igg1 class, with an affinity of 2.19×10-8 m-1. due to high specific reactivity, this antib...

OBJECTIVES This study aimed to demonstrate if the addition of anti-inflammatory treatment to antibiotic therapy shows any superiority to the treatment with antibiotic only. METHODS Forty-nine Wistar rats were divided into 7 groups. Pyelonephritis was performed by E. coli injection to upper pole of kidneys except control group. Group 2 was not treated. Ceftriaxone, ketoprofen, "ceftriaxone + k...

INTRODUCTION L,L-ethylenedicysteine (EC) is a new carrier of technetium Tc 99m (99mTc) with a lower affinity to plasma albumin in comparison with diethylenetriamine pentaacetic acid (DTPA). We compared 99mTc-EC scan with 99mTc-DTPA scan in diuretic renography for patients with obstructive uropathy. MATERIALS AND METHODS Thirty-three patients with upper urinary tract obstruction were randomly ...

This study demonstrates the normal technetium-99m diethylenetriaminepentaacetic acid ([99mTc]DTPA) renal scan in pregnant patients with transplanted kidneys. Five pregnant renal transplant patients had seven [99mTc]DTPA renal studies to assess allograft perfusion and function. All scans showed the uteroplacental complex. The bladder was always compressed and distorted. The transplanted kidney w...

A 45-year-old man presented with loin pain and burning micturation. He had a positive Bilharzial titre and impaired renal function. Ultrasonography (USG) revealed right hydroureteronephrosis and a thickened bladder wall with areas of calcification. A diuretic 99mTc – DTPA scan (technetium-99m diethylene triamine penta acetic acid) showed features of obstruction in both the kidneys. Cystoscopy s...

Background: Assessment of renal lesions and deficiency accurately remains critical in the diagnosis congenital anomalies kidneys urinary tracts (CAKUT) children. Advanced imaging such as Magnetic resonance Imaging (MRI) Diffusion weighted (DWI) allows structural functional insufficiency to be detected. Currently, radiomics machine learning models are being explored full-automated diagnostic too...

Technetium-99m methoxyisobutylisonitrile (99mTc-MIBI) uptake is known to be increased in breast cancer because of increased blood flow from angiogenesis and heightened metabolism. We performed a 99mTc-MIBI scan in a patient with mammary Paget's disease. The patient had underlying invasive cancer in the same side of the breast. 99mTc-MIBI scan exhibited a scintigraphic image of the uptake from t...
