PURPOSE We performed this network meta-analysis to compare the diagnostic value of 4 imaging methods (magnetic resonance imaging, positron emission tomography, computed tomography, and diffusion-weighted imaging) for diagnosing lymph node metastases in cervical cancer. METHOD Diagnostic tests regarding different imaging methods to diagnose lymph node metastases in cervical cancer were retriev...

PURPOSE In this work a general method is presented that enables clinicians to rapidly select Rotating shield brachytherapy (RSBT) emission angles based on the patient-specific tradeoff between delivery time and tumor dose conformity. Cervical cancer cases are used as examples. METHODS Anchor plans with high dose conformity but infeasible delivery times are generated with a fine emission angle...

background: the aim of this study was to determine bioavailability heavy metal concentrations of cu, cd, cr, co and zn and health risk assessment in different types of klang district, selangor (malaysia) urban surface soil using in physiologically based extraction test in vitro human digestion model. methods: a total of 76 urban surface soil was sampled based on seven different types of land us...

air pollution is a major concern of new civilized world, which has a serious toxicological impact on human health and the environment. it has a number of different emission sources, but motor vehicles and industrial processes contribute the major part of air pollution.according to the world health organization, six major air pollutants include particle pollution, ground?level ozone, carbon mono...

OBJECTIVE To ascertain whether fluorodeoxyglucose positron emission tomography is indicated for clinical staging of superficial cancer, we sought to determine if it accurately classifies tumor (T), regional nodal (N), and distant metastases (M), including distinguishing high-grade dysplasia (Tis) from invasive cancer (T1). METHODS Fifty-eight superficial esophageal cancer patients had preoper...

indium is a heavy metal belonging to group iiia. it is used as a radioimaging and chemotherapeutic agent in diagnosis and also in the treatment of cancers. it is believed that indium may interfere with iron metabolism and reduce cell growth in cancer tissue. the present report was established to study the binding of iron and indium to apo-transferrin (apo-tf) and to identify amino acids involve...

Introduction: To investigate the effects of breathing cycle and tree diaphragm motions on prostate cancer tumors standard uptake value (SUV) during positron emission tomography (PET) and to correct it. Materials and methods: Respiratory motion traces were simulated on the common patient breathing cycle and tree diaphragm motio...

Neurotensin receptor 1 (NTS1) is overexpressed on a variety of cancer entities; for example, prostate cancer, ductal pancreatic adenocarcinoma, and breast cancer. Therefore, it represents an interesting target for the diagnosis of these cancers types by positron emission tomography (PET) [...].

[C-11] choline positron emission tomography ([C-11] choline PET) has been expected to be one of the new PET modalities similar to [F-18] fuluorodeoxyglucose positron emission tomography (FDG-PET), which has spread worldwide as a gold standard of PET oncologic imaging. However, there has been no report on [C-11] choline PET used for detection of colorectal cancer, which is one of major targets o...
