A review of MRI studies in Africa with special focus on quantitative MRI: Historical development, current status and the role of medical physicists.

This scoping review provides overview on the historical and major developments, current status, quantitative magnetic resonance (MR) studies and the role of medical physics bodies in MR imaging in Africa. The study analyzed MRI availability in 32 (59 %) of the 54 African countries. South Africa and Egypt have the most dominant MR systems.

Biological Evaluation of Grid versus 3D Conformal Radiotherapy in Bulky Head and Neck Cancer.

Unlabelled: Grid radiotherapy is one of the treatment techniques applied to treat patients with advanced bulky tumors.

Purpose: This study aims to estimate the difference in biological and dosimetric parameters of the grid radiotherapy technique for the treatment of bulky head and neck (H and N) tumors and compare it with conventional conformal radiotherapy.

Subjects And Methods: Three-dimensional conformal and grid radiotherapy were designed by the Monaco treatment planning system (TPS).
