For decades MRI has been utilized for diagnosing spine pathology. However, like many imaging modalities utilized today, a conventional MRI is a static study. The spine is a complex, dynamic structure whose loading characteristics change with the position of the spine and the type and direction of force applied. This gives rise to dynamic pathologies that are often masked if attempted to be imaged using conventional MRIs. This is where a weight-bearing MRI (WBMRI) shines. We report the case of a 66-year-old female in whom an L3-L4 synovial facet cyst was diagnosed on a WBMRI.

Purpose: The Japanese Investigation Committee (JIC) classification for osteonecrosis of the femoral head (ONFH) is based on the necrotic area relative to the weight-bearing surface on anteroposterior (AP) radiographs or central coronal MRI. Discrepancies exist between these methods, potentially related to the AP necrosis area. This study evaluated these discrepancies and the extent of AP necrotic lesions.

Background: Bipartite medial cuneiform bone (BMC) is located at the Lisfranc joint of the midfoot, and it represents a rare variant involving two separate ossification centers in the medial cuneiform bone. Although BMC is typically asymptomatic, it can become clinically relevant under conditions of trauma or chronic stress, affecting foot stability.
Case Report: The current imaging report describes a 48-year-old female presenting with chronic dorsal midfoot pain, worsened by extended standing and ambulation.

Introduction: Quadriceps tendon rupture is a traumatic injury where the quadriceps detaches from the patella, disrupting the knee's extensor mechanism. Bilateral ruptures, first documented in 1949, are rare, with an incidence of 0.17-2.

Atlantoaxial osteoarthritis (AAOA) is a clinical syndrome that consists of occipitocervical pain and cervical rotation limitation. Its clinical recognition is often deficient leading to misdiagnosis and suboptimal treatment. The incidence of AAOA varies from 5% in the sixth decade to as much as 18% in the ninth decade of life.

Purpose: To investigate positional lumbar changes by weight-bearing MRI in low back pain (LBP) patients with hypermobile joints (Beighton score ≥ 4).
Methods: Patients referred to weight-bearing MRI went through a clinical examination, including Beighton's test, answered back pain-related questionnaires, and were hereafter imaged in supine and standing in a 0.25-T MRI unit.
