37 11.3. Magnetic Resonance Imaging in Francophone West Africa Presenter: Aziagba Dogbévi, Polyclinique Saint Joseph Lome Togo Author: Aziagba Dogbévi Introduction: The magnetic resonance imaging (MRI) is one of the very few still available radiological modern methods in poor countries. The high cost of installation could justify the rarity of this technology. Many countries especially in sub-Saharan Africa do not have MRI, and schools radiology training in these countries conform their training technologies available on site. In the West African region which consists of 16 countries, including eight French countries, only 3 of its 8 francophone countries have at least an MRI machine. In order to evaluate the practice of this new technology of our discipline in Francophone Africa, we initiated a study that aims to: - Determine the profile of radiographers working on an MRI - Identify their difficulties - Exposing their wishes and recommendations for improvement of MRI practices in Africa The study was conducted during the months of November and December 2013 through the three Francophone countries of West Africa has at least an MRI namely Cote d'Ivoire, Senegal and Togo, and involved a total of 13 centers of Radiology with MRI machine. An opinion survey was sent to radiographers or radiological technologist working in MRI in these centers. Methods: The survey focused on 7 themes: MRI Radiographers; initial training of radiographers; special training in MRI and continuing education; MRI centers; protocol, configuration and MRI images realization; Great difficulties; Best wishes of radiographers. Results: 13 MRI centers. MRI radiographers: 8 answer our questions (5 Togoleses, 2 Ivorians and 1 Senegalese). 62.5% have never worked in MRI before. Initial training of radiographers: 3 years for all. For 75% this training didn’t include MRI. Special training in MRI: 75% hadn’t received training. The MRI centers: 84 % are low magnetic field machine (0.23T to 0.35 T). Protocol and MRI images realization: 37.5% arrived to modify exam's protocol; 62,7% not succeeds. Wishes: Practical training in MRI. 11.4. MRI of the liver - the imaging protocols of the Central Hospital of Central Finland Presenter: Tiina Nousiainen, Central Hospital of Central Finland Author: Tiina Nousiainen Introduction: The Central Hospital of Central Finland performs the second highest number of liver resections in Finland. Over 30 liver resections and over 170 hepatic MRI scans were being done in 2013. Metastases are the most common malignant lesions in the liver and also the most common reason for liver imaging. Two thirds of the liver resections executed in our hospital are being done to patients with liver metastasis colorectal cancer liver metastases. Magnetic Resonance Imaging (MRI) of the liver has improved significantly due to the progress in technology. Stronger magnetic fields, better coils and advanced sequences have made MRI play a bigger role in hepatic imaging. It is used for detecting, locating, quantificating and characterizing hepatic lesions. At our hospital MRI is not routinely used for pre-operative imaging but rather for characterization of undefined lesions seen in other cross sectional imaging like computed tomography. Our hepatic MRI protocols are based on unenhanced T1-, T2- and diffusion weighted sequences and dynamic multiphase fluorotriggered contrast-enhanced T1W imaging. Methods: The usage of contrast agent is necessary when doing a hepatic MRI as the enhancement properties form a basis for the characterization of the lesions. The contrast agents can be divided into gadolinium based chelated agents (GBCA) and non-GBCA. Results: The non-GBCAs include hepatobiliary agents and reticuloendothelial agents. The classification is based on their chemical properties, biological distribution and mechanism of action. Liver specific contrast agents give greater liver-to-lesion contrast compared to gadolinium chelates. The most used contrast agent in liver MR imaging in our hospital is GBCA but also a hepatocyte specific gadolinium based contrast agent is being used in selected cases. 12. NUCLEAR MEDICINE 12.1. Sterile and septic inflammation: imaging properties of 67 Gacitrate versus in-house manufactured 99mTc-ECDG Presenter: Je'nine Horn-Lodewyk, Department of Nuclear Medicine, Universitas Academic Hospital, Bloemfontein, South-Africa Authors: J. Horn-Lodewyk, A.C. Otto, J.M. Wagener, J.R. Zeevaart and G. Joubert Introduction: The imaging properties of the newly synthesized in-house manufactured (IHM) technetium-ethylenedicysteine-deoxyglucose (99mTc-ECDG) and the established 67Ga-citrate were compared in sterile (zymosan) and septic (Escherichia coli) inflammation models. The aim of this study was to determine whether there is a difference in the degree of inflammation detection for IHM 99mTc-ECDG (99mTc-ECDG) and 67Gacitrate in rabbits with induced septic and sterile inflammation. Methods: IHM 99mTc-ECDG static imaging at 0-6 hour (h) and SPECT/CT at 2- and 4 h. 67Ga-citrate statics at 24- and 48 h and SPECT/CT at 24- and 48 h. Regions of interest on the infected right, versus uninfected left area and expressed as mean percentages. Results: The mean % uptake for the static images of the IHM 99mTc-ECDG group one from 0-6 h was 66.57% and for the IHM 99mTc-ECDG group two from 0-6 h was 66.10%. These did not differ significantly, p=0.78. The mean % uptake for static images of the 67Ga-citrate group one 24-48 h was 82.10% and the mean % uptake for 67Ga-citrate group two 24-48 h was 78.25%. 67Ga-citrate gave better results than IHM 99mTc-ECDG yet the latter compared favourable in both the sterile and septic inflammation model. 12.2. Accuracy of Nuclear Medicine Technologist Reporting on Bone Scintigraphy: A case Study from Sudan Presenter: Suliman Salih, 1 Faculty of Applied Science, Taibah University., Al-madinah Al-munawarah, KSA,2 National Cancer Institute - University of Gezira, Sudan Authors: Suliman Salih Introduction: Development in radiologic technologist (radiographer) reporting role over the past four decades has been necessary to deliver and expand clinical imaging services. In developing countries, radiologic technologist reporting is become a requirement, where there is shortage in medical staff. The objective of this study is to assess the accuracy of nuclear medicine technologist reporting on bone scintigraphy, in comparing with nuclear medicine physician as reference standard. Methods: The study statistical assessed the nuclear medicine technologist (NMT) reporting on 100 bone scans in comparing with nuclear medicine physician report as reference standard. The study was carried out at National Cancer Institute, University of Gezir Results: This study revealed the accuracy, specificity and sensitivity of nuclear medicine technologist reporting were 97.4%, 95.8% and 97 respectively, in comparing to of nuclear medicine physician. Conclusion: This study provide evidence that nuclear medicine technologists can reporting on bone scintigraphy accurately, if they exposed to a formal training in nuclear medicine image reporting. 12.3.

This presentation is aimed at analysing the number of patients, age group, treatment progress report, cancer preponderance among cases like cancers of the cervix, prostate, breast and most common scan performed as well as the challenges and contribution of radiographers in nuclear medicine. Methods: * A total of 637 Radionuclide bone scan patients during the period were presented . The diagnosis, biodata and results were analyzed using descriptive means. Patients for other scans were excluded. * Tc-99m
