Optimisation of T2 and T2* sequences in MRI for better quantification of iron on transfused dependent sickle cell patients.

This work aimed to investigate the effect of different shim techniques, voxel sizes, and repetition time (TR) on using theT2 and T2* sequences to determine their optimum settings to investigate the quantification of iron in transfused dependent sickle cell patients. The effect of each of these parameters was investigated on phantoms of different Gadolinium (Gd) concentrations, on 10 volunteers and 25 patients using a1 5T MRI Philips scanner. No significant difference between the three shim techniques was noticed in either T2 or T2* sequence measurements.

Sudanese paediatric residents' perception towards training environment in Sudan Medical Specialisation Board, 2020.

The training environment is a determinant of learning outcomes. Paediatric residents spend most of their training programme activities in hospitals and related health centres. Measurement of the educational environment for residents is important to detect strengths and weaknesses and to ensure quality training.
