The effect of chemotherapy type and timing among the other factors on patency of totally implantable vascular access devices in colorectal carcinoma.

Purpose: Catheter-related complications are observed in infusion of chemotherapy, and these were encountered with targeted therapies. Our principle is to study non-mechanical effects of type and initiation time of chemotherapy among the other factors on patency of totally implantable vascular access devices (TIVAD) inserted in patients with colorectal carcinoma.

Methods: This is a one-center retrospective cohort study.

Diagnostic value of diffusion-weighted magnetic resonance imaging: differentiation of benign and malignant lymph nodes in different regions of the body.

Introduction: To evaluate the value of diffusion-weighted magnetic resonance imaging compared with conventional magnetic resonance imaging (C-MRI) for the differentiation of benign from malignant lymph nodes in different regions of the body.

Patients And Methods: A total of 31 patients ranging in age from 18 to 75 years (mean age: 53 years) were included in this study. The patients were examined using a 1.
