Stress fracture shin mri7/31/2023 7 In addition to the exam being faster, it is also cheaper. 6According to Mann et al, with a 5 minute protocol MRI utilizing T2 FAT SAT sequence in axial section, there is no difference in diagnostic performance in detection and grading of tibial bone stress injuries amidst an abbreviated 5-min and a complete 25-min MRI test, with a substantial inter-reader agreement. 6It is the most precise test when the patient has symptoms and may help discriminate among MTSS and advanced stress fracture. ![]() MRI is becoming a popular imaging test in cases of suspected MTSS, essentially because periosteal and bony edema are clearly seen – sensitivity is about 78% to 89%. 6CT scan has sensitivity of 42% and specificity of 100%. 6, 7īone scintigraphy sensitivity in diagnosing MTSS is around 74% to 84%, but overdiagnosis and false-positive findings have been reported. 6Radiographs are usually the primary level in the orthopedic imaging analysis however, it can be normal – sometimes it demonstrates periosteal reaction or callus formation. The need for imaging investigations in the context of a precise history and physical examination has been doubted, but imaging tests are required when the concerning stress fracture is important. 5 It must distinguish from chronic exertional compartment syndrome which is usually present throughout the exercise and suddenly reduces after exercise. 5 MTSS diagnosis can be established when a recognizable pain is present on palpation of the posteromedial tibial margin for 5 cm or more. Physical activity should produce pain throughout or following the exercise. This article aims to report an unusual case of MTSS diagnosed by MRI in a sedentary person.
