Background: Radiological students face a complex deci-sion-making process, with four years of study and one year of internship before graduation. After graduation, they apply for a career in their chosen specialty, depending on available positions. Some radiologic technology subspecialties in Sau-di Arabia face workforce shortages. Graduates from radiolog-ic sciences programs have the opportunity to choose from six subspecialties during their internship year. Motivations, percep-tions, and expectations for their future influence their selection of subspecialties. Aim of Study: This study discovers the most influential factors affecting Saudi radiological students and technologist choice of subspecialty in radiology field at the Kingdom of Sau-di Arabia. Methods: A comprehensive search was conducted across multiple databases including Medline, Embase, CINAHL, Scopus, Web of Science, IEEE Xplore Digital Library, CADTH, and WorldCat. All English-language papers documenting the factors influencing the choice of students and radiologic tech-nologist in Saudi Arabia. Results: Researches state that MRI modality was the most preferred specialty for the participants. The most important factor which has the direct effect on the choice of internship subspecialty was future job opportunities and personal interest. No promising advance or gain (limited career) rose to be the most important factor affecting the technologist to avoid X-ray specialty. Conclusion: Saudi radiological technologist and students were influenced mostly by future job opportunities in that field and personal interest, when they considered their future sub-specialty. MRI modality was the most preferred specialty in the  internship rotation, while interventional radiology was the least modality chosen in the internship
