Radiation Exposure In Interventional Procedures, G. K. Korir, B. O. Ochieng, J. S. Wambani, I. K. Korir, C. Y. Jowi

Imaging & Diagnostic Radiology, East Africa

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 …

Avoiding Unnecessary Fine-Needle Aspiration Cytology By Accuractely Predicting The Benign Nature Of Thyroid Nodules Using Ultrasound, Sudhir Vinayak, Joyce Sande

Imaging & Diagnostic Radiology, East Africa

Objective: The objective of this study was to describe a reliable ultrasound based index scoring system based on ultraound characteristics to identify benign thyroid nodules and avoid unnecessary fine needle aspiration cytology.

Materials and Methods: Patients undergoing ultrasound-guided fine-needle aspiration cytology (FNAC) for thyroid nodules were evaluated prospectively. A total of 284 patients were evaluated from November 2005 to November 2011. There were 284 nodules. Any solid or partly solid focal nodule in the thyroid gland was included in the study. Cysts with no solid component were excluded. We used LOGIQ 9 (GE Healthcare) scanner equipped with a 10--14 MHz …

Establishing The Quality Management Baseline In The Use Of Computed Tomography Machines In Kenya, Geoffrey K. Korir, Jeska S. Wambani, Ian K. Korir, Bernard O. Ochieng

Imaging & Diagnostic Radiology, East Africa

The objective of this study was to assess the level of compliance to quality assurance and image quality standards in computed tomography facilities in Kenyan hospitals. A quality assurance inspection and physical image quality assessment in eighteen representative computed tomography facilities were completed. A quantitative method was developed and used to score the results obtained from the physical image quality measurements using the American Association of Physicists in Medicine (AAPM) water phantom. Inspection was done in order to establish the level of compliance with internationally recognized standards such as those stipulated in the European Guidelines Quality Criteria for Computed Tomography …
