OBJECTIVE Conus medullaris syndrome (CMS) is a clinical neurologic syndrome caused by a conus medullaris lesion. CMS is a heterogeneous entity with various etiologies such as trauma or a space-occupying lesion. Multiple cases of CMS following spinal anesthesia have been reported, but CMS after radioisotope (RI) cisternography has not yet been reported. METHODS We present four patients who dev...

To assess the influence of the ureter on renal washout during 99mTc-DTPA diuresis renography, ureteral images were reviewed in 42 children (median age: 5 mo) referred for hydronephrosis. Sixty-minute acquisitions were obtained in hydrated patients under bladder drainage. Furosemide was injected at 30 min. An abnormal ureter was defined as an intense and continuous image of greater than 10 min. ...

Clearance of inhaled 99mTechnetium-labelled diethylene triamine pentacetate (99mTc-DTPA) from the lung, an index of pulmonary alveolar epithelial permeability (PAEP), was measured in 13 patients with cardiogenic interstitial pulmonary oedema (CIPO) and in 7 patients with adult respiratory distress syndrome (ARDS). Thirty-five normal subjects (22 nonsmokers and 13 smokers) were evaluated as cont...

Transmission-emission scanning of the thorax with a flood source of technetium-99m (99mTc), autologous 99mTc labelled red blood cells, and diethylenetriaminepenta-acetic acid (99mTc DTPA) allows measurement of thoracic tissue thickness and blood and interstitial volume per pixel of the gamma camera image. Volume of blood or interstitium per pixel divided by pixel area gives the thoracic tissue ...

Objective: The development of new radiopharmaceuticals capable specifically imaging cancer is an important research area. For this reason, the aim study to investigate cell binding novel developed nanoradiopharmaceutical ([99mTc]Tc-nab-PTX) on HT-29 line (human colorectal adenocarcinoma cells).
 Material and Method: In study, nab-PTX was labeled with [99mTc]Tc, labeling efficiency in vitro...
