Nowadays, a huge number of papers have documented the ability of diffusion magnetic resonance imaging (D-MRI) to highlight normal and pathological conditions in a variety of cerebral, abdominal, and cardiovascular applications. To date, however, the role of D-MRI to investigate musculoskeletal tissue, specifically the cancellous bone, has not been extensively explored. In order to determine potentially useful applications of diffusion techniques in musculoskeletal investigation, D-MRI applications to detect osteoporosis disease were reviewed and further explained.

The popliteal hiatus is a complex region, formed by the confluence of various structures connecting the meniscus, popliteal tendon, tibia and fibula. The main structures that can be found are the three popliteomeniscal fascicles (anterior, postero-inferior and postero-superior), the lateral and posterior meniscotibial ligaments, the popliteofibular ligament and the meniscofibular fascicle. These structures can be identified in most cases using magnetic resonance imaging, and their ‘static’ assessment can be performed. Arthroscopic assessment is useful in identifying and testing ‘dynamically’ the integrity of the structures around the popliteal hiatus. Injuries or abnormalities of the popliteal hiatus and its structures could result in meniscal hypermobility and subluxation; however, these injuries are often unrecognized. Possible abnormalities in this region, apart from the well-known bucket-handle meniscal tear, are the Wrisberg Type III discoid meniscus, and meniscal fascicles tears.

Background. Pathological changes in the size and structure of Hoffa’s fat pad can cause pain in the anterior section of the knee joint. Therefore, they should be diagnosed. The objective of the paper is to improve the diagnostics of Hoffa’s fat pad disease on the basis of a detailed study of the clinical anatomy of the infrapatellar (Hoffa’s) fat pad and magnetic resonance imaging (MRI) findings in normal and pathological conditions.Materials and Methods. Protocols of 86 MRI examinations of knee joints with anterior knee pain syndrome and no clearly defined traumatic history nor positive clinical tests indicating damage to the intra-articular and periarticular elements with identified structural changes in the fat pad were selected retrospectively. The control group consisted of data from 24 examinations of asymptomatic knee joints. In all cases, the pathology was confirmed during diagnostic and therapeutic arthroscopy.Results. The MRI findings showed the normal structure of the infrapatellar fat pad, as well as pathological changes in the form of tearing, local edema, diffuse edema, synovial proliferation and fibrosis. Depending on the location and type of changes, 4 pathological syndromes were identified: “classic” Hoffa’s disease — 49 (57%) cases, infrapatellar synovial fold syndrome — 11 (13%), infrapatellar synovial fold separation syndrome — 6 (7%), and impingent syndrome of upper lateral adipose tissue — 20 (23%) cases.Conclusions. To identify a pathology, a precise synchronization of clinical and morphological changes is required. Accurate differentiation of syndromes is possible due to knowledge of the detailed anatomical and magnetic-resonance features of the fat pad in normal and pathological conditions. This allows to diagnose the cause of pain in the anterior sections of the knee joint, specify the diagnosis, and choose the optimal plan of treatment.

Objectives In daily clinical practice, the assessment of the thickness of the cauda equina on lumbar spine magnetic resonance imaging is an important parameter. However, its relevance to the size of the dural sac in non-pathological conditions is unknown. To examine the relationship between the size of the dural sac and the apparent thickness of the cauda equina nerve root using lumbar spine magnetic resonance imaging in non-pathological conditions. Methods We retrospectively measured the dural sac diameter and vertebral body diameter, counted the apparent number, and calculated total cross-sectional area of the cauda equina, dural sac ratio and the area of one apparent nerve root of cauda equina in 100 cases. Spearman's rank correlation coefficient ( ρ) was used. Results Dural sac ratio and diameter were positively correlated with the area of one apparent nerve root ( ρ=0.77, P<0.001; ρ=0.74, P<0.001; respectively) and negatively correlated with the apparent number of cauda equina in a single cross-section ( ρ=–0.63, P<0.001; ρ=–0.52, P<0.001; respectively). Conclusions A larger dural sac ratio and diameter was associated with an apparently thicker cauda equina and lower visible number. In a larger dural sac, the physiologically clumped and apparently thicker cauda equina should not be misdiagnosed as pathological.

The formation of anterior cruciate ligament cysts is one of the rare non-traumatic forms of knee joint lesions with unexplored etiopathogenesis. The formation of cysts of the anterior cruciate ligament is characteristic of younger people. The disease can be asymptomatic, being detected by chance during magnetic resonance imaging of the knee joint, in the case of a symptomatic course of the disease, the main complaints are chronic nonspecific pain, limitation of terminal flexion and extension of the joint, rarely mechanical symptoms. Magnetic resonance imaging is the method of choice for diagnosing these pathological conditions of the knee joint. The arthroscopic aid allows you to successfully combat this condition, while in the absence of a threat to the stability of the joint, debridement of the joint is performed, and if the stability of the joint is threatened, the issue of reconstruction of the anterior cruciate ligament is considered.
