By adding hands-on ultrasound experience using live patients proctored by radiologists for final year medical students, in the space of 2 weeks, an effective ultrasound learning model for undergraduate medical students can be provided. This model should be considered in the curricular design.

Adding a 1-week dedicated radiology rotation to fifth- or sixth-year students after they finished the standard radiology course is beneficial to students. This type of vertical radiology curriculum is valuable and should be incorporated into formal medical school curricula.

Background:Ultrasound (US) is widely used among physicians. There has been no standardized curriculum in US for undergraduate medical students. This study aimed to assess the US image acquisition skill of final year medical students after adding 2 weeks dedicated radiology rotation.Methods:At our institution, there are two hospital affiliations. Two-week radiology rotation was added for the final-year students of one affiliation. These students had a chance to do the US in real-life clinical settings proctored by radiologists. At the end of the academic year, US image acquisition skill was assessed by objective structured clinical examination (OSCE) in students from both affiliations.Results:From 48-final-year medical students, 28 students finished the 2 week radiology rotation. OSCE mean score of the students who received radiology rotation was significantly higher than other groups with a score of 65.5 compared to 53.3, respectively (P = 0.006). The student background characteristics had no relationship with the OSCE score (P = 0.565).Conclusion:Results showed that exposure through a dedicated radiology rotation in only 2 weeks is helpful to improve the US skill of the medical students regardless of their background performances. Exposure to live patients is essential for students' experiences. OSCE can be used as a standardized assessment tool.

Non-surgical reduction of the intussusception is the first line treatment in children with intussusception. Among various radiological reduction techniques, barium enema reduction of the intussusception under fluoroscopy has been widely used in Thailand while pneumatic reduction under fluoroscopy has become popular in teaching hospitals. To our knowledge, ultrasound-guided hydrostatic reduction of the intussusception by saline enema (UGHSE) has never been used in Thailand. We reported 9 cases using UGHSE with 100% success rate without complication.
