Background and Objectives: Positron emission tomography (PET) scan is a radionuclide imaging technique with implications in diagnostic and therapeutic oncology. Due to the complexity in the technique and cost factor, this technique has not been popular among the general and specialty dental practitioners. This survey study utilizes the Likert item to evaluate the intensity of response toward the technical and practical aspects of PET scan in dentistry. Materials and Methods: A representative population of 500 respondents was chosen by randomization. These respondents were either postgraduates or staff of various dental specialties. A close-ended questionnaire was provided inclusive of the Likert items. Simple arithmetic percentages were calculated to evaluate the knowledge and practice. One-way ANOVA test was done to evaluate the Likert items and regression analysis was done to find a correlation between the questions asked in attitude. Result: Statistically significant values (P = 0.0010) were obtained while evaluating the Likert items. Linear regression analysis showed a strong correlation between the questions asked in attitude. Conclusion:The overall impression of the survey revealed that the knowledge of the respondents was above optimum. However, the responses in attitude revealed a lack of practical knowledge and inhibitions pertaining to prescribe PET scan in dentistry.

“…Já na Medicina Nuclear, o paciente é o próprio emissor da radiação ionizante, uma vez que esta técnica implica na prévia administração de substâncias radioativas a ele, desta forma, a produção da imagem do paciente para finalidades diagnósticas é chamada de imagem por emissão. as cintilografias e as tomografias por emissão de pósitrons [3,4] . A possibilidade do uso de radioisótopos na Medicina trouxe diversos avanços e conquistas no decorrer dos anos; alguns destes avanços podem ser observados na própria Tabela 1.…”

“…A intensidade desse campo de radiação no entorno do paciente está diretamente relacionada à quantidade de substância radioativa administrada, chamada de atividade, bem como com as características físicas de cada radioisótopo utilizado, incluindo a meia-vida física, tipo de emissão radioativa e energia da radiação emitida, incluindo também, fatore anatômicos específicos de cada paciente. Esse campo de radiação é formado pela pouca interação entre a radiação ionizante eletromagnética (fótons) emitida pelas substâncias radioativas administradas e o corpo humano [1,2,4] .…”

Patients undergoing Nuclear Medicine procedures, whether diagnostic or therapeutic, become radioactive sources for a period of time until the radioactive substance they incorporate is completely eliminated from their organisms. As a consequence, radioactive patients may expose other individuals and the environment to ionizing radiation. In order to reduce these exposures, radioprotective care with these patients is usually required. However, the small amount of radioactive material administered in diagnostic procedures leads to the question of the real need for such care and, even if this need is proven, it is still necessary to establish the period of its validity.There are no scientific studies in the literature to establish such care and its adequacy according to the clinical needs of each patient. Answers to these questions are linked to the true exposure potential these patients offer to other individuals, as well as the radiological risks arising from these exposures and radiation doses. Thus, this study primarily aims to evaluate these exposure potentials based on the study of patient-received radiopharmaceutical retention and excretion bikinetics, as well as to evaluate the radioprotective care to be implemented in diagnostic Nuclear Medicine either to reduce or control family exposures. and other individuals of the Society who may be exposed to these patients.

Can positron emission tomography be more than a diagnostic tool? A survey on clinical practice among radiation oncologists in India

Abstract: Our survey revealed the vast difference between literature suggestions and actual clinical practice on the use of PET in radiotherapy. Additional training and standardization of protocols for use of PET in radiotherapy is essential for fully utilizing the capability of PET.
