introduction: the radioimmunoscintigraphy (ris) has found widespread clinical applications in  tumor  diagnosis.  human  epithelial  mucin,  muc1,  is  commonly  over  expressed  in  adenocarcinoma including 80% of breast cancers and represents a useful target for ris. the pr81  is  a  new  murine  anti-muc1  monoclonal  antibody  that  was  found  to  react  with  the  membrane  extracts of se...

We studied the pharmacokinetic properties of two human monoclonal antibodies to colon carcinoma cells and their ability to detect tumors in nude mice bearing primary human colon carcinoma xenografts. The 16-88 and 28A32 monoclonal antibodies are immunoglobulin M class human antibodies produced by cell lines derived from peripheral blood lymphocytes from patients with colon carcinoma. The patien...

Breast cancer has become one of the leading causes of death in women today. Many researches are ongoing to develop more effective imaging methods for early diagnosis of breast cancer. The application of nuclear medicine techniques to study patients with breast cancer has recently raised its profile, particularly in the investigation ‘indeterminate mammographic lesions’. Radio labeled monoclonal...

Breast cancer radioimmunoscintigraphy targeting HER2/neu expression is a growing field of work in nuclear medicine research. In this study, trastuzumab was successively labeled with [(67)Ga] GaCl3 after conjugation with DOTA-NHS-ester. The conjugates were purified by molecular filtration, the average number of DOTA conjugated per mAb was calculated and total concentration was determined by spec...

UNLABELLED Aortic dissection is among the most common of fatal conditions of the aorta. Prompt and accurate diagnosis of the site and extent of the lesion is necessary for adequate therapy. However, this catastrophic disease, characterized by extensive damage to smooth muscle cells, lacks specific signs and symptoms. As a result, the diagnosis is still frequently missed today and a new diagnost...

Kinetic analysis with probability mapping is an objective method of serial image analysis applicable to radioimmunoscintigraphy. The technique is described and subjected to clinical testing by comparing the prediction of biopsy histology from the probability map in patients coming to operation. In those with ovarian cancer undergoing second-look laparotomy after completing full courses of chemo...
