  1. CT & MRI – What is Expected from the Radiological Technologists Dr. Harsha DissanayakeMBBS, M.Phil, MD(Radiology) Dip. Neurovascular Diseases (France) Consultant Radiologist & Senior Lecturer Faculty of Medical Sciences University of Sri Jayewardenepura

  2. Radiographer Radiological TechnologistMedical Imaging Technologist

  3. Who is a Radiological Technologist? • a trained health care professional • who performs medical imaging by • producing high quality images which is useful to diagnose and treat injury or disease. • patient’s diagnosis and treatment is often dependent on the images produced. • He is an important member of the Health care team.

  4. Health Care Professional • undertakes a specialized set of tasks • enjoys considerable work autonomy • engaged in creative and intellectually challenging work • Patients place a great deal of trust in them • strict codes of conduct • Ethical and moral obligations

  5. What should be the goal – when encountered with a patient • To generate the best possible, • Highest quality, • Appropriate images – which will be used to arrive at the diagnosis / or to treat.

  6. How to achieve this goal ? • Asses the patient’s problem – get the information • Analyze • Set the goal clear • Formulate a plan to achieve the goal • Workout the plan performing the tasks • Self evaluate your images – “Is this the best possible images that I can generate?”

  7. Quality control of the procedure • Inferior quality images / study • Area of interest inadequately covered / all sequences not included ……….etc May lead to – Inaccurate interpretation / wrong diagnosis – Repeated exposure – Radiation hazards to the patient / self / staff – Additional cost – Additional time

  8. Competency ? • expertise and knowledge of patient handling • physics, anatomy, physiology and radiology to assess patients • develop optimal radiologic techniques to plan and evaluate – resulting radiographic images. • Should be able to spot “what is not normal” – pathology • Radiation Protection • Quality Control

  9. How the competency is gained? • High school Diploma – Certificate course • University Degree BSc in Diagnostic Radiography/Diagnostic Imaging – 3yrs • Can specialize in-house or through a university course as a postgraduate in CT, MRI, Nuclear Medicine ….. with opportunities to gain an MSc in their field.

  10. CT & MRI – What is Expected from the Radiological Technologists • Before / During / After the procedure • Check the identity and the requested investigation • Check the consent • explaining the procedure • ensure that the patent has had the correct preparation • Keep the emergency tray ready

  11. clothing, ensure that there are no metal objects that may interfere • Check the clinical details – if inadequate make a note of the patents problem & relevant details. Get previous imaging Ix reports/films • If the requested investigation is not clear / inappropriate, always discuss with the referring clinician • Check the patients data sheet / questionnaire – whether it is appropriately filled • Are there any contraindications / Allergies?

  12. During the scanning • Radiation dose • All medical radiation exposures must be justified and the radiation levels optimized • Radiation to the patient (in diagnostic studies), staff and the general public are to be kept As Low As Reasonably Achievable (the ALARA principle)

  13. Protocols • Protocols are mere guidelines. • Has to modify according to the individual patients problem – when ever necessary • Timing of the procedure • Whether to give contrast or not • Timing of the contrast injection • Arterial / venous / late phases • Oral /rectal contrast • MRI – additional sequences - ? Haemorrage / Calcification / stroke ……..

  14. Example 1 • 60yrs • Male • Haematuria • Ix. – CT KUB

  15. CT KUB – Normal / no calculi

  16. Are you happy?

  17. Late finding

  18. 48 yrs / liver lesion in USS Ix. - Triple phase CT Arterial Portal venous

  19. Ix. - Triple phase CT Arterial Portal venous

  20. Ix. - Triple phase CT Arterial Portal venous
