Three-dimensional and 3-Tesla MRI morphometry of knee meniscus in normal and pathologic state.

Introduction: To conduct a morphometric analysis of intact and torn menisci using isotropic meniscus plane three-dimensional (3D) reconstructions on 3-Tesla MRI and compare 2D versus 3D MRI for meniscus tear characterization.

Materials And Methods: One hundred thirty three normal menisci from 92 patients (39 male, 53 female), and 38 arthroscopy-proven torn menisci from 36 patients (23 male, 13 female) were evaluated using 3D isotropic multi-planar MRI reconstructions and 2D MRI. Two observers measured the tibial plateau height and area, meniscal height, axial plane cross-sectional areas, and extrusion of intact menisci.

Upper limb peripheral neuropathy in sickle cell anemia: MR neurography appearances.

Sickle cell anemia is an inherited disorder with many systemic complications. Peripheral neuropathy related to this disorder has been sparsely reported. We report an interesting case of upper limb peripheral neuropathy from sickle cell disease with emphasis on MR neurography appearances and electrophysiology correlation.

Quantitative assessment of diabetic amyotrophy using magnetic resonance neurography-a case-control analysis.

Objectives: To quantitatively characterize diabetic amyotrophy (DA), or diabetic lumbosacral radiculoplexopathy, and compare with controls using magnetic resonance neurography (MRN).

Methods: Forty controls and 23 DA cases were analyzed qualitatively and quantitatively. Cross-sectional areas (CSAs) of bilateral L3 through S2 lumbosacral nerve roots, femoral nerves, and sciatic nerves (proximal and distal measurements) were measured.

Diffusion tensor imaging of diabetic amyotrophy.

Objective: To qualitatively and quantitatively characterize the nerves of patients with diabetic amyotrophy (DA) using magnetic resonance neurography (MRN) with diffusion tensor imaging (DTI).

Materials And Methods: Forty controls and 13 DA cases were analyzed. 1.

Role of MR Neurography in Groin and Genital Pain: Ilioinguinal, Iliohypogastric, and Genitofemoral Neuralgia.

Objective: Chronic neuralgia of the border nerves (ilioinguinal, iliohypogastric, and genitofemoral) is difficult to diagnose and treat clinically. We examined the role of MR neurography (MRN) in the evaluation of border nerve abnormalities and the results of treatments directed at the MRN-detected nerve abnormalities.

Materials And Methods: This retrospective cross-sectional study included 106 subjects with groin or genital pain (mean [± SD] age, 50.

Carpal boss in chronic wrist pain and its association with partial osseous coalition and osteoarthritis - A case report with focus on MRI findings.

The carpal boss is a bony prominence at the dorsal aspect of the 2(nd) and/or 3(rd) carpometacarpal joint, which has been linked to various etiologies, including trauma, os styloideum, osteophyte formation, and partial osseous coalition. It may result in symptoms through secondary degeneration, ganglion formation, bursitis, or extensor tendon abnormalities by altered biomechanics of wrist motion. We present a case of symptomatic carpal boss with the finding of a partial osseous coalition at the 2(nd) carpometacarpal (metacarpal-trapezoid) joint and highlight the magnetic resonance imaging (MRI) findings of carpal boss impingement and secondary osteoarthritis.

Imaging of hidradenitis suppurativa and its complications.

We present a 56-year-old man with known diabetes mellitus and a 10-year history of hidradenitis suppurativa (HS) and highlight, through MR imaging findings, the relentless natural progression of the disease, characterized by recurrent exacerbations of abscesses and fistulae and complications of perianal fistulae and sacral osteomyelitis. We also demonstrate the appearance of this condition on PET-CT with F-18 FDG, which was performed for staging after postexcision tissue specimen revealed well-differentiated squamous cell carcinoma. The association of arthritis and possible dactylitis was also manifested in our patient.
