Abstract
To compare respiratory triggered diffusion‐weighted single‐shot echo planar imaging (RT DW‐SS‐EPI) and T2 weighted turbo spin echo imaging (T2W TSE). To determine apparent diffusion coefficients (ADCS) of focal liver lesions and normal liver parenchyma. The main sources of data for the study are patients from the following teaching Hospitals attached to Bapuji Education Association, J.J.M. Medical College, Davangere. 30 patients with focal liver lesions and additional 10 healthy volunteers (to know normal diffusion pattern and ADC values of liver) with no focal liver lesions were studied. Among the 30 included patients(with 85 lesions), there were 9 with 23 HCCs, 2 with 4 cholangiocelluar Carcinomas, 8 with 36 metastatic lesions, 11 with 22 benign lesions (6 hemangiomas in 4 patients, 9 cysts in 4 patients, 7 hydatid cysts in 3 patients). DWI was associated with significantly higher detection rate of FLLs when compared to T2WI. (P <0.001). The number of malignant FLLs detected with DWI (62 out of 63‐98.4%) was highly significant than that detected with T2 WI (P<0.001). There was no significant difference between the T2 weighted imaging and DWI for the detection of HCCs alone. The diffusion‐weighted MRI sequence is a useful diagnostic tool with no need to use contrast media, and it can contribute to accurate diagnosis and discrimination between benign and malignant hepatic masses. The use of DWI was superior for the detection of malignant liver lesions than the use of T2 weighted imaging.
