Diagnostic Value of Diffusion-Weighted MR Imaging in Differentiating T- Stage of Urinary Bladder Cancer: With Histopathological Correlation

Urinary bladder cancer is the second most prevalent kind of cancer affecting the urinary tract. Magnetic resonance imaging (MRI) is a useful imaging modality for the radiological examination of the urinary bladder and the prostate gland because of its high tissue contrast, multiplanar imaging capabilities, and the potential of tissue characterisation. The purpose of this research was to examine the relationship between the apparent diffusion coefficient (ADC) and the histologic grade of bladder cancer and to assess the use of DW-MRI as a staging tool for this disease. Thirty individuals with bladder mass were included in this trial. It was discovered that DWI has a higher overall accuracy (stage by stage) than T2WI and post contrast image (83.3% vs. 56.7% and 42.9%, respectively). In low grade tumours, the mean ADC value is high, whereas in high grade tumours it is low, with a cut off value of 0.83 mm2/s x10-3. Our research led us to the conclusion that DW-MRI is a reliable and secure tool for detecting and locally staging urinary bladder cancer. The histological grade of a tumour may be predicted using the ADC value as well. As a result, DWI may become a standard procedure for imaging malignancies in the urinary bladder.
