“…MRI has an added advantage for noninvasive evaluation of the pancreatic parenchyma, biliary and pancreatic ducts, adjacent soft tissues, vascular structures, and composition of AP-associated fluid collections in a single examination [17,19,20]. However, MRI abdomen without and with IV contrast with MRCP does not provide coverage and adequate evaluation of the bowel to assess an alternative diagnosis of bowel ischemia, perforation, etc.…”

“…It measures the random movement of the water molecule against the cell membrane barrier., A diffusion gradient is applied to the desired area with DWI and after a certain period of time, the signal is collected from the same area [1,20,21]. If the amount of cells per unit area is high (such as malignant tissue), water molecules cannot move quickly and remain in the same area where the gradient is sent thus, a high signal is obtained with diffusion restriction which is the restriction of the movement of water molecules [1,[20][21][22][23]. If the amount of cells per unit area is low, such as in benign tissues, water molecules will traverse, freely and randomly rotate without any restriction, causing decreased signal intensity [1,20,23].…”

Most common urinary system cancer is the Bladder cancer(BC), more common in men (M/F: 3), is associated with both genetic and environmental factors.,two most well-known environmental factors are smoking and occupational exposures.Smoking is associated with 25-65% of BC cases, %50 average. Urothelial cancers are common in occupations that use paint, textiles, rubber and petroleum products. Among the chemical substances; O-toluidine, 2-naphthylamine, benzidine, 4-amino-biphenyl and nitrosamines are particularly related with the BC. Our objective in this systematic review is to indicate the value and aid of CT and MRI in the diagnosis of bladder cancer.

“…Diffusion-weighted magnetic resonance imaging (DW-MRI) is the best sequence that can be used during emergency settings because of its short acquisition time, the absence of radiation, and its high resolution [5,6]. The pancreas is both an exocrine and endocrine organ, and it therefore has a rich blood supply and is expected to have good diffusion characteristics.…”

Background The role of diffusion-weighted magnetic resonance imaging (DW-MRI) in the diagnosis of acute pancreatitis is assessed in this study by measuring the apparent diffusion coefficient (ADC) values in acute pancreatitis and comparing them with a control group. The aim of this study is to compare those two groups thus supporting the diagnosis of this disease. Sixteen patients with acute pancreatitis and 16 control participants underwent diffusion-weighted imaging with b values of 0, 200, and 800. ADC maps were generated from the DW-MRI and ADC values, which were calculated for the pancreas, and the results of the two groups of patients were compared. Results The mean pancreatic ADC value in the acute pancreatitis group (1.15 10(−3) mm(2)/s ± 0.28) was significantly lower than in the normal group (1.6 10−3 mm(2)/s ± 0.2). A threshold ADC value of 1.38 10−3 mm(2)/s yielded 81.25%, specificity of 93.75%, positive predictive value of 92.9%, negative predictive value of 83.3%, and accuracy of 91.8%. Pancreatic ADC values were significantly lower in patients with acute pancreatitis than in the control group. Conclusion Diffusion-weighted magnetic resonance imaging could be an important supportive tool in the diagnosis of acute pancreatitis.
