Prevalence and Predictive Features of CT-Derived Nonalcoholic Fatty Liver Disease in Metabolically Healthy MACS.

Objective: Patients with mild autonomous cortisol secretion (MACS) are at increased risk of cardiometabolic outcomes, such as hyperglycemia, metabolic syndrome, and cardiovascular diseases. Nonalcoholic fatty liver disease (NAFLD) is also associated with increased cardiometabolic risk. We aimed to investigate the prevalence and predictors of NAFLD in metabolically healthy subjects with MACS.

Soft tissue tumor imaging in adults: European Society of Musculoskeletal Radiology-Guidelines 2024: imaging immediately after neoadjuvant therapy in soft tissue sarcoma, soft tissue tumor surveillance, and the role of interventional radiology.

Objectives: An update of the first European Society of Musculoskeletal Radiology (ESSR) consensus on soft tissue tumor imaging in 2015 became necessary due to technical advancements, further insights into specific entities, and the revised WHO classification (2020) and AJCC staging system (2017). The third part of the revised guidelines covers algorithms and techniques beyond initial imaging: (1) Imaging after neoadjuvant therapy in soft tissue sarcoma, (2) sarcoma surveillance, and (3) special aspects, including surveillance of non-malignant entities and the role of interventional radiology.

Materials And Methods: A validated Delphi method based on peer-reviewed literature was used to derive consensus among a panel of 46 specialized musculoskeletal radiologists from 12 European countries.

This second of three papers covers algorithms once histology is confirmed: (1) standardized whole-body staging, (2) special algorithms for non-malignant entities, and (3) multiplicity, genetic tumor syndromes, and pitfalls.

Materials And Methods: A validated Delphi method based on peer-reviewed literature was used to derive consensus among a panel of 46 specialized musculoskeletal radiologists from 12 European countries.

Soft tissue tumor imaging in adults: European Society of Musculoskeletal Radiology-Guidelines 2023-overview, and primary local imaging: how and where?

Objectives: Early, accurate diagnosis is crucial for the prognosis of patients with soft tissue sarcomas. To this end, standardization of imaging algorithms, technical requirements, and reporting is therefore a prerequisite. Since the first European Society of Musculoskeletal Radiology (ESSR) consensus in 2015, technical achievements, further insights into specific entities, and the revised WHO-classification (2020) and AJCC staging system (2017) made an update necessary.

Comparison of the fibrosis degree using acoustic radiation force impulse elastography and diffusion-weighted magnetic resonance imaging in chronic hepatitis cases.

Objective: The aim of this study was to investigate the correlation of fibrosis stages in cases of chronic hepatitis by comparing shear wave elastography and diffusion-weighted magnetic resonance imaging.

Methods: A total of 46 chronic hepatitis patients with an age range of 20-50 years were classified into three groups based on their fibrosis stages. Comparison group 1: the presence of fibrosis (S0 and S1≤); comparison group 2: the presence of significant fibrosis (≤S2 and S3≤); and comparison group 3: the presence of cirrhosis (≤S4 and S6).

Present Status of Musculoskeletal Radiology in Europe: International Survey by the European Society of Musculoskeletal Radiology.

No official data exist on the status of musculoskeletal (MSK) radiology in Europe. The Committee for National Societies conducted an international survey to understand the status of training, subspecialization, and local practice among the European Society of Musculoskeletal Radiology (ESSR) partner societies. This article reports the results of that survey.

Imaging of Pelvic and Femoral Fixation Hardware: Normal Findings and Hardware Failure.

Good outcomes following treatment of pelvic ring injuries, acetabular fractures, and femur fractures rely on restoration of native pelvic or limb alignment, anatomical reduction and rigid stability of articular fractures, and early postoperative mobilization. Multiple surgical approaches, reduction aids, and orthopaedic implants are available to stabilize these fractures. Despite best practices, complications including hardware failure, nonunions, malunions, and infections occur.

Imaging Following Fractures of and Around the Knee.

Related to fractures of and around the knee, inappropriate technical factors related to the surgery, severe comminution of the fracture, early overly arduous rehabilitation of the patient, and patient-related noncompliances may have the potential for the risk of inadequate fixation and other complications. Loss of fixation, malunion/nonunion, infection, arthritis, arthrofibrosis, and symptomatic hardware are among postsurgical complications that may necessitate further reconstructive techniques. In this review, complications that may be encountered in the postsurgical period of fractures involving the patella, supracondylar femur, and tibial plateau are described.

Siatic nerve: beyond the sacral foramen.

Sciatica may result from pathologies affecting the nerve both in its intraspinal and extraspinal course. In daily routine, the vast majority of cases are caused by herniation of the lumbar discs compressing the neural roots. Extraspinal causes of sciatic pain are usually underestimated and the imaging study may be completed after reporting the lumbar MRIs.

Hemangioma of the Zygomatic Bone.

Benign masses arising from facial bones have been reported several times in the literature. Hemangiomas are one of the uncommon benign tumors. In this study, the authors aimed to present a rare patient of zygomatic intraosseos hemangioma and their management.

Carpal bone cysts: MRI, gross pathology, and histology correlation in cadavers.

Purpose: Intraosseous cysts of carpal bones are frequently observed on routine imaging examinations of the wrist. There is controversy regarding the underlying pathogenesis of these cysts. In this study, we aimed to investigate the magnetic resonance imaging (MRI) appearance of intracarpal bone cysts in correlation with histologic analysis, using cadaveric wrists.

Muscle involvement in two Behçet cases: magnetic resonance imaging and histology findings.

Behçet's disease (BD) is a systemic vasculitis with a classic trio of symptoms of oral aphthous ulcers, genital ulcers, and ocular lesions that present in a relapsing fashion. Despite these most frequently encountered symptoms of the disease, other systems such as vascular, gastrointestinal, and neurological involvements can also occur. Muscular involvement is rare, and there are only a few cases in the literature, which were reported mainly in a pediatric population.

Collar-type osteophyte of the femur in young adults: is it a harbinger of intra-articular osteoid osteoma?

Variable clinical and radiological findings for intra-articular osteoid osteoma (OO) of the hip joint make its diagnosis difficult. Because radiographs commonly do not identify the nidus, MR imaging becomes the second line of study. However, because the appearance varies, findings on MR images can be confusing.

Apparent diffusion coefficients of sacroiliitis in patients with established ankylosing spondylitis.

Aim: To compare apparent diffusion coefficients (ADCs) of sacroiliac joints (SIJs) in ankylosing spondylitis (AS) patients during advanced-active and advanced-nonactive stages.

Materials-methods: AS patients with chronic-active (n=19), chronic-nonactive (n=6), and controls with normal SIJs (n=8) were included. Mean ADCs through 43 subchondral bone marrow edema lesions (SBMELs) were calculated.

Radiological followup of the evolution of inflammatory process in sacroiliac joint with magnetic resonance imaging: a case with pyogenic sacroiliitis.

Pyogenic sacroiliitis (PS) is an acute form of sacroiliitis that mostly starts with very painful buttock pain. Here in this case, the followup magnetic resonance (MR) images of a 49-year-old male patient with PS is displayed. After his sacroiliitis was documented by MR images, he was treated with the combination of rifampicin plus streptomycin and moxifloxacin.

Value of DWI in visual assessment of activity of sacroiliitis in longstanding ankylosing spondylitis patients.

Objective: To test contrast to noise ratios (CNRs) of both diffusion-weighted (DW) images and contrast enhanced images in terms of the visual assessment of activity in sacroiliitis of ankylosing spondylitis (AS) patients.

Materials And Methods: The study included 21 patients with AS. All patients were examined with STIR, FST1/Gd and DWI (b = 0,600).

"Water-lily sign" as a rare finding of spinal hydatidosis.

Hydatid disease (HD) is a common parasitic infestation in some developing countries. Hydatid disease may affect many organs in the body, but the most affected are the liver and lungs. Hepatic and pulmonary HD is relatively easier to diagnose because of the frequency of pathognomic features and its order in the differential diagnosis list.

Magnetic resonance imaging of the temporomandibular joint disc: feasibility of novel quantitative magnetic resonance evaluation using histologic and biomechanical reference standards.

Aims: To use the ultrashort time-to-echo magnetic resonance imaging (UTE MRI) technique to quantify short T2* properties (obtained through gradient echo) of a disc from the human temporomandibular joint (TMJ) and to corroborate regional T2* values with biomechanical properties and histologic appearance of the discal tissues.

Methods: A cadaveric human TMJ was sliced sagittally and imaged by conventional and UTE MRI techniques. The slices were then subjected to either biomechanical indentation testing or histologic evaluation, and linear regression was used for comparison to T2* maps obtained from UTE MRI data.
