The basic principles of diffusion weighted imaging required for qualitative and quantitative interpretations are discussed along with briefing of technical aspects of performing diffusion weighted MRI of body. The objective of the study was to evaluate diagnostic contribution of diffusion weighted MRI in detecting lesions in body and whether ADC values are helpful to differentiate benign from malignant lesions

50 patients with different pathologies in abdomen, pelvis, breast, neck and extremities were included in this study. 14 patients of hepatic pathologies, 7 patients of breast pathologies, 15 patients of pelvic pathologies, 3 of pancreatic pathologies, 10 of pathologies of extremities and 1 of parotid pathology were included in the study. Two radiologists independently reviewed the signal intensity of the lesions on diffusion weighted MRI with a b factor of 50, 400, 800 s/mm2. Mean ADC values were calculated.

There were statistically significant differences between ADC values of benign and malignant lesions( p< 0.001). The mean ADC value of benign lesions was significantly higher than that of malignant lesions (P < 0.01).

Diffusion weighted imaging is helpful in detecting the lesions in body and helpful in differentiating the benign and malignant pathologies
