coronary heart disease (cad) is the leading cause of death specially among elderly. coronary angiography is the best diagnostic method in the patients, but is unfortunately an invasive procedure with its inherent risks. myocardial perfusion scan is a noninvasive and sensitive method for evaluation of cad and is suggested by many investigators in recent years. in this study, 64 patients who had ...

BACKGROUND The non-invasive Cxbladder urine test system has demonstrated clinical utility in ruling out urothelial carcinoma (UC) in patients with asymptomatic microscopic hematuria (AMH), suggesting that the number of invasive diagnostic tests, including cystoscopy, used in this patient population may be reduced by Cxbladder testing prior to conducting a full urological work-up. The aim of thi...

Background: Most cancer studies focus on exploring non-invasive biomarkers for cancer detection. In the present study, we sought to investigate the expression level of microRNA-21 (miR-21), as a potential diagnostic marker, in serum and stool samples from 40 patients with colorectal cancer (CRC) and 40 healthy controls. Methods: Quantitative real-time RT-PCR was applied to determine the relativ...

The investigation and treatment of coronary disease impose a significant burden on health service resources. Catheter coronary angiography remains the gold standard for the investigation of suspected coronary disease. Given the invasive nature and high costs of invasive coronary angiography, there is an increased interest in noninvasive methods to image the lumen of the coronary arteries. Recen...

AIMS/BACKGROUND This study was performed to ascertain the diagnostic accuracy rate of non-invasive tests in patients with presumed uveal melanomas scheduled to be treated with either irradiation or cyclochoroidectomy. METHODS One hundred consecutive patients who had non-invasive tests followed by fine needle aspiration biopsy (FNAB) as prior alternative treatment were analysed retrospectively...
