BACKGROUND: Prosthetic mesh implants are widely used in hernia surgery. To show long-term mesh-related complications such as shrinkage or adhesions, a precise visualization of meshes and their vicinity in vivo is important. By supplementing mesh fibers with ferro particles, magnetic resonance imaging (MRI) can help to delineate the mesh itself. ...

The presence or absence of inguinal LVL and the responsible lymphatic vessels were determined using the ...

Magnetic resonance imaging (MRI) is used routinely in many fetal care centers for the evaluation of the fetus with congenital diaphragmatic hernia (CDH). Current MRI strategies focus on identifying the type of hernia and its contents, as well as calculating fetal lung volumes, in order to plan appropriately for neonatal ...

We report the sonographic and CT findings in a patient with an epiploic appendage strangulated within a Spigelian hernia sac. The patient presented with a small, tender, palpable mass, which, at sonography, was located within the abdominal wall, lateral to the rectus abdominis muscle, and had the appearance of an ...

Magnetic resonance (MR) imaging technique and findings in the setting of athletic pubalgia, including injury at the rectus abdominis/adductor aponeurosis, are becoming widely recognized. A subset of these patients is treated with various pelvic floor repairs, mesh reinforcements, and tendon releases. Most of these patients do well after intervention, but ...

Bochdalek hernias (BHs) are produced in the posterolateral area of the diaphragm.

Vasitis or inflammation of the vas deferens is a rarely described condition categorized by Chan & Schlegel1 as either generally asymptomatic vasitis nodosa or the acutely painful infectious vasitis. Clinically, infectious vasitis presents with nonspecific symptoms of localized pain and swelling that can be confused with other, more common conditions ...

Physiologic bowel activity on In-111 octreotide imaging is commonly seen. However, on occasion, normal bowel activity may mimic lesions in the abdomen, which can be very difficult to differentiate, particularly after surgical intervention. We report a case of focal bowel activity simulating a lesion in a patient who had an ...

Because articular cartilage is avascular and has no intrinsic capacity to heal itself, physical damage to cartilage poses a serious clinical problem for orthopedic surgeons and rheumatologists. No medication exists to treat or reconstitute physical defects in articular cartilage, and pharmacotherapy is limited to pain control. Developments in the field ...

Our objective is to outline the utility of adrenal venous sampling (AVS) with measurements of metanephrine to normetanephrine ratios for diagnostic localization of phaeochromocytoma in a patient with normal plasma levels of catecholamines. A 53-year-old-woman was referred for evaluation of recurrent pheochromocytoma following a right adrenalectomy 14 years earlier. Diagnosis of ...

To investigates the impact of nonrigid motion correction on pixel-wise pharmacokinetic analysis of free-breathing DCE-MRI in patients with solitary pulmonary nodules (SPNs). Misalignment of focal lesions due to respiratory motion in free-breathing dynamic contrast-enhanced MRI (DCE-MRI) precludes obtaining reliable time-intensity curves, which are crucial for pharmacokinetic analysis for tissue characterization. ...

Cortisol and the glucocorticoid receptors (GRs) play an important role in fish osmoregulation, while the involvement of the mineralocorticoid receptor (MR) and its putative ligand 11-deoxycorticosterone (DOC) has been poorly investigated. In this study, we assessed the implication of DOC and MR in rainbow trout (Oncorhynchus mykiss) osmoregulation during hypo- ...

Twenty-nine patients with OPLL were studied. According to the plaques' continuity to the ...

Conventional autologous chondrocyte transplantation in the ankle often requires tibial or fibular osteotomies with potential morbidity for the patient. Advances in biotechnology and surgical techniques have resulted in the development of matrix-associated chondrocyte implantation (MACI). As the chondrocyte-loaded scaffold can be applied arthroscopically, this procedure is especially useful for the ...

Two horses presented with a history of severe lameness that was localised to the area around the second phalanx (P2) of one forelimb. Radiographs of the second phalanx of both horses were unremarkable, apart from some smooth periosteal new bone production on the dorsum of P2. Magnetic resonance imaging revealed ...

Tarsal coalition represents abnormal fusion among two or more tarsal bones and is a frequent cause of foot and ankle pain. The coexistence of calcaneonavicular and talocalcaneal coalitions in the same foot has been rarely cited in the literature. We report three cases of rigid flatfoot associated to a double ...

Acute and chronic elbow pain is common, particularly in athletes.

Magnetic resonance (MR) imaging is important in diagnosing musculoskeletal injuries in horses. However, there is still much to learn regarding the significance of lesions identified in equine MR images. Of particular importance is the clinical significance of signal change as a function of pulse sequence. We hypothesized that a resolution ...

Multiple authors have debated the contribution of intertubercular groove morphology to biceps tendon pathology. It has been proposed that the shallow groove, combined with the supertubercular ridge of Meyer, predisposes patients to bicipital disease. In this study we hypothesized that there would be a correlation between bicipital groove morphology and ...

We investigated changes in dimensional (volume, cross-sectional area, ...

BACKGROUND: Ballet dancers require extreme range of motion of the ankle, especially weight-bearing maximum plantar flexion (en pointe). In spite of a high prevalence of foot and ankle injuries in ballet dancers, the anatomy and pathoanatomy of this position have not been sufficiently studied in weight-bearing. Magnetic resonance imaging (MRI) ...
