The course NUCLEAR MEDICINE is a compulsory course in the fourth year of the Integrated Undergraduate and Graduate Study of Medicine in English, in VIII. (summer) semester. It consists of 12 hours of lectures, 6 hours of seminars and 12 hours of practicals, a total of 30 hours (2 ECTS credits). It takes place in Clinical Department of Nuclear Medicine and in the lecture hall of Clinical Hospital Center Rijeka.
OBJECTIVES OF THE COURSE: The goal of this course is to encounter students with open ionizing radiation sources used in nuclear medicine (NM) for diagnostic and therapeutic purpose: radionuclides (RN). Students should learn about manipulation and use of the radionuclides, radiopharmaceuticals (RF) and instrumentation that will enable them, as future general practitioners, to correctly understand clinical indications in an individual patient. Methods and rules in radiation protection (Basic Safety Standards) should be acquired, as well as contamination and decontamination concept, specifically for patients receiving RN, nursing staff, other persons in contact with a patient (family) and the environment. The advantages and importance of hybrid imaging methods (SPECT/CT, PET/CT) are introduced, especially in diagnostics, but also in therapy, with consequences regarding radiation protection. Students should acquire general knowledge regarding molecular nuclear medicine imaging and personalized medicine based on theranostics. The importance of nuclear medicine and other methods in thyroid diagnostics and therapy should be conceived.
COURSE DESCRIPTION:
The basic physics of ionizing radiation, radioactive decay, production of
radionuclides, and specific RN used in NM are studied. Interactions of ionizing radiation with matter, including persons and environment are discussed. Radionuclides used in NM are demonstrated, their
production (generator, cyclotrons), storage and clinical (diagnostic and therapeutic) use. Optimal characteristics of RN for diagnostics and therapy, the most common RN used in nuclear medicine
(technetium- 99m, iodine isotopes and fluorine- 18) are analysed. Synthesis of radiopharmaceuticals (RF) and crucial role of their biodistibution is explained. Complexity of radiation exposure arising from hybrid
imagining is mentioned. Methods and rules in radiation protection, primarily from gamma radiation are being demonstrated in «hot laboratory», contamination and decontamination concept, specifically for
persons, patients and environment. Instrumentation basics- gamma detectors, gamma camera are studied. Imaging diagnostic procedures with RN and RF are described including a static and dynamic
(planar) scintigraphy, the types of emission tomographies (single photon- SPECT and positron- PET), hybrid (multimodality) imaging (SPECT/CT, PET/CT), and information on PET/MR. Functional diagnostics of thyroid diseases (thyroid scintigraphy, iodine accumulation), thyroid and neck sonography and fine needle aspiration biopsy are discussed. Diagnostics and therapy of benign and malignant thyroid diseases is described. Radioiodine therapy of benign and malignant diseases is presented. Therapeutic use of other radionuclides and radiopharmaceuticals is mentioned.
Radiopharmaceuticals and imaging protocols for bone scintigraphy and SPECT/CT, lung scintigraphy and SPECT, SPECT/CT diagnostics of neuroendocrine tumours and inflammation are demonstrated. Sentinel
lymph node scintigraphy is mentioned. Nuclear medicine procedures and imaging methods in cardiology, nephrourology, paediatrics, neurology and gastroenterology are discussed.
PET/CT diagnostic procedures in oncology (18F-FDG) and other indications are presented. Concept of theranostics and personalized medicine is presented.
LEARNING OUTCOMES: Acquisition of basic and specific competencies defined by objectives, basic knowledge and skills described in this syllabus. The limiting factor is ionizing radiation zone. As students are not allowed to handle radioactive sources (according to the radiation protection legislature), the education is limited to demonstration of work with RN and instructions on specific procedures (use of radiation detectors) by professionals. Required knowledge is adopted theoretically; however practical work is partly enabled by active participation in seminars and practicals (thyroid ultrasound).
BASIC COMPETENCIES that student should acquire are:
1. Radiopharmaceuticals - students should define the term radionuclide and radiopharmaceutical, they should be able to list the most important and common diagnostic radionuclides and their physical
properties (gamma energy and physical half- life).
2. Instrumentation - should be able to describe basics of gamma camera (principle of gamma detection), (planar) scintigraphy and basics of reconstruction in SPECT and PET tomography.
3. Students should understand and describe advantages and importance of hybrid technologies (SPECT/CT and PET/CT).
4. Students should be able to describe the most common nuclear medicine imaging radiopharmaceuticals, diagnostic procedures and methods, the physical properties of the most commonly used diagnostic radionuclides and diagnostic procedures in nephrourology, oncology, cardiology, pulmology, paediatrics and neurology.
5. Students should explain the therapeutic procedures in nuclear medicine - distinguish diagnostic from therapeutic applications, summarize physical, chemical and biological grounds for radionuclide therapy
application. They should understand the characteristics of an ideal therapeutic radionuclide and name several examples.
6. Define thyroid disease diagnostics and therapy - describe physical properties of iodine-131 and of other iodine isotopes (iodine- 123, iodine- 125 and iodine- 124), understand the aim of iodine uptake test and thyroid scintigraphy in benign thyroid diseases that could be treated with iodine 131. Comprehend the role of thyroid ultrasound and fine needle aspiration biopsy.
7. Understand the aim and explain the procedure of radioiodine ablation in patients with thyroid cancer.
Describe the role of iodine-131 whole body scintigraphy and tomography (SPECT/CT) in thyroid cancer patients.
8. Students should define the term personalized therapy and theranostic in nuclear medicine (radioiodine therapy, therapy of neuroendocrine tumours).
9. Describe open radioactive sources in medicine and recognize the patient as a radioactive source, remember three main physical principles of radiation protection, distinguish difference in handling open
and sealed radioactive sources (x-ray, CT), understand the possibility of contamination.
SPECIFIC COMPETENCIES: As students are not allowed to handle radioactive sources (according to the radiation protection legislature), the education is limited to demonstration of work with RN and
instructions on specific procedures.
1. Obtaining radionuclides (99mTc) from the generator column- understand the elution of the generator.
2. Radiopharmaceutical labelling - understand the mechanism of biodistribution of radiopharmaceuticals, difference between static and dynamic radiopharmaceuticals.
3. Gamma camera scintigraphy, computer analysis of static and dynamic studies – explain the difference between them, understand application of the most important radiopharmaceuticals.
4. Understand which radiopharmaceuticals (static or dynamic) enable emission tomography studies (SPECT, PET) and why.
5. Hybrid imaging diagnostics (SPECT/CT, PET/CT) - understand the basics and advantages of hybrid instrumentation and contribution of „low dose“CT-a (LDCT) in SPECT and PET.
6. Neck and thyroid ultrasound-understand the importance of ultrasound in thyroid diseases, especially in thyroid nodules, contribution of fine needle aspiration biopsy in diagnostics of thyroid malignancies.
COURSE STRUCTURE: Classes are organised in the form of 12 hours of lectures, 6 hours of seminars and 12 hours of practicals, a total of 30 hours (5 weeks). Lectures take place in the Lecture hall, Clinical Hospital Center Rijeka or depending on the epidemiological situation will be online - Merlin or MS Teams. Seminars and practicals take place place in Clinical Department of Nuclear Medicine. Practicals are coordinated with the lectures, and after the topic is elaborated at the lecture, it should be demonstrated during the consecutive practical. At the end of the class, students must pass the final oral exam. In order to take final oral exam, seminar presentation must be completed (presented and submitted).
