INTRODUCTION Radiology or Roentgenology as it was once known was derived from the name of a German physicist called Wilhelm Conrad Roentgen, who discovered x-rays in 1895 and received the first Nobel Prize in physics as a result. Radiology is the use of x-rays to produce images for interpretation and diagnosis of diseases of anatomical structures and organs. Notwithstanding its late entry into medicine, the impact of x-rays has been astoundingly phenomenal. DEPARTMENTAL OBJECTIVES TRAINING Undergraduate : The students are made to understand the physical principles of image formation of structures, beginning with simple x-rays. To teach radiographic/radiological anatomy, correlating same with conventional anatomy. To stress the significance and use of contrast media in radiology, emphasizing their indications and contraindications. To familiarize students with the use of sound waves from special materials (piezoelectric crystals) to produce images, in Ultrasound Scanning. To acquaint Students with the rudiments of mammography examinations. To acquire skills in the use of Computerized Tomographic Scanning. To introduce students to Magnetic Resonance imaging. To initiate the use of interventional procedures such as embolization of vessels, uterine fibroid embolization, MRI-guided breast biopsy. Residency Training Supporting the Lagos State University Teaching Hospital, the department trains Residents towards attaining the fellowships of the various postgraduate medical colleges. CLINICAL SERVICES Aims at providing high level diagnostic care in the hospital. This is done by the Consultant Radiologists in the department, who support the Lagos State University Teaching Hospital. RESEARCH To conduct research towards advancement of knowledge and improvement of medical practice in general. ACTIVITIES OF THE DEPARTMENT Plain Radiography, Special Investigations such as Intravenous Urography (IVU), Hysterosalpingography (HSG) e.t.c., Ultrasound Scan Clinics, Mammography Clinics, Undergraduate Lectures/Tutorials. Residency Lectures / Tutorials / Seminars Clinicoradiological Meetings with clinical departments to discuss interesting films. Departmental Continuing Medical Education Meetings Hospital Grand Rounds and Mortality Review Meeting. MODE OF INSTRUCTION TO STUDENTS This is undertaken through: Lectures using multimedia demonstrations, Tutorials & Seminars. Clinical Demonstrations Ultrasound Scan Clinics, participation in special investigation. Attendance of Continuing Medical Education and Mortality Review sessions One week lectures each during clinical postings in Surgery, Medicine, Paediatrics, Obstetrics and Gynaecology. MODE OF ASSESSMENT Students are required to complete Log books which are signed by their lecturers to reflect their attendance at lectures and procedures or practical demonstrations. At least 75% attendance is required. End of course examination. This is in form of: Film viewing sessions through multimedia projector with five stem true or false questions. OSCE or steeple chase.
