The aim of this study was to estimate radiation doses patients and staff are exposed to during interventional procedures (IPs), compare them with the international diagnostic reference levels and to develop initial National Diagnostic Reference Levels. The IP survey was undertaken as the initial task of which, retrospective data were collected from the only four Kenyan hospitals carrying out interventional radiology and cardiology procedures at the time of the study. Real-time measurement of radiation dose to patients and staff during these procedures was done. To the patients, kerma-area product (KAP) and fluoroscopy time measurements were done using an in-built KAP …

Objective: To analyse inter-observer variation between a neuroradiologist and neurosurgeon in the MRI diagnosis of lumbar nerve root compression. Although lumbar MFI is primarily analyzed and reported by a radiologist, neurosurgeons often analyse it independently as they have sufficient clinical background as well as radiological expertise to diagnose most spinal pathologies on Magnetic Resonance Imaging (MRI).
Methods: Retrospective analysis was carried out for images of 54 patients who underwent MRI between March and July 2010 of lumbar spine with suspected lumbar disc herniation and nerve root compression, at Aga Khan Hospital, Karachi, Pakistan. One fellowship trained neuroradiologist and one neurosurgeon …
