Dynamic study of the finger interphalangeal joint volar plate —motion analysis with magnetic resonance cinematography and histologic comparison
ConclusionOur study analyzed the full range of motion dynamic VP shape of the PIP joint using MRCF. This contributes to a more precise understanding of the complex interaction of the VP with the PIP joint and may facilitate evaluation of clinical cases such as VP avulsion or pulley rupture.

Comparison between conventional MRI and weight-bearing positional MRI reveals important differences in radiological measurements of the patellofemoral joint
ConclusionSignificant differences in important patellofemoral morphology measurements were observed between supine and standing MRI scanning positions. These were unlikely due to physiological factors such as changes in joint loading but rather induced by slight differences in knee flexion angle. This emphasises the need to standardise knee positioning during scanning, particularly for weight-bearing positional MRI before clinical use. (Source: Skeletal Radiology)

Musculoskeletal steroid injections in pregnancy: a review
AbstractPregnant women experience a wide range of musculoskeletal pain disorders, which include general ailments occurring during pregnancy, exacerbation of pre-existing conditions, or pregnancy-specific pain/inflammatory conditions. There are significant concerns and knowledge gaps surrounding the safety, dosage, and potential long-term effects of several drugs used during pregnancy. Our article reviews the use of focal steroid injections during pregnancy. A mixture of case studies, meta-analyses, and randomised controlled trials have shown at least there is no adverse side effect to the mother or baby from maternal use o...

A comparison of smooth and sharp kernel CT reconstructions in the detection of unilateral sacral fractures
ConclusionThe use of smooth kernel reconstructions improved the sensitivity of CT for the detection of SF compared to the sharp kernel reconstructions usually used and regardless of the experience of the radiologist. Smooth kernel reconstructions should, therefore, be scrutinized in patients with suspicion of SF. (Source: Skeletal Radiology)

Aggressive gluteal fibromatosis: a rare case associated with spontaneous superior gluteal artery pseudoaneurysm
We present the case of a 33-year-old man who presented with a right gluteal fibrous mass identified on magnetic resonance imaging (MRI), which was associated with a pseudoaneurysm originating from the right superior gluteal artery on serial follow-up with MRI and computed tomography. No intervention was done, and after conservative management, spontaneous thrombosis of the pseudoaneurysm was developed. Such imaging finding is the first report of a spontaneous development of pseudoaneurysm caused by deep fibromatosis, which could be a life-threatening condition and should be considered when dealing with deep fibromatosis an...

Ultrasound-guided nerve block prior to biopsy of suspected neurogenic tumors: safety and feasibility in a pilot study
ConclusionNerve block prior to ultrasound-guided biopsy of potentially neurogenic tumors is a safe and feasible technique. Further study is needed to determine the extent to which nerve block can decrease intra-procedural pain and reduce or eliminate the need for sedation during biopsy. (Source: Skeletal Radiology)

Factors influencing patient understanding of information on radiology examinations
ConclusionPatients with college degrees understood more on information documents. Females read more of the documents than males and had a higher objective understanding. Reading grade level did not affect understanding. (Source: Skeletal Radiology)

Ulnar positive variance associated with TFCC foveal tear
ConclusionThis study revealed that TFCC foveal tear induces 0.56 mm of radiologic UPV, which was successfully corrected after arthroscopic transosseous TFCC foveal repair. Therefore, UPV associated with TFCC foveal tear should not be misdiagnosed as an UIS. Also, when ulnar shortening osteotomy is planned in case of UIS combined with TFCC foveal tear, the amoun t of UPV induced by TFCC foveal tear should be considered to prevent over-shortening.

Calcifying fibrous tumor: a rare case in the foot
We report the case of a 25-year-old man who presented with a mass in the medial aspect of the right foot that was first noted 4 years earlier. Medical attention was sought due to perceived increase in size as well as increasing pain in the right foot. The patient had no limitations in activity but reported worsening discomfort while walking. An anteroposterior radiograph obtained at first presentation demonstrated a large calcified soft mass in the medial aspect of the foot. Contrast-enhanced MRI showed a mildly enhancing 6.5 cm × 2.5 cm × 8.5 cm mass, hypointense on T1- and T2-weighted images, infiltrating ...

Erdheim-Chester disease: diffusion-weighted imaging and dynamic contrast-enhanced MRI provide useful information
We present a case of a 70-year-old woman who was referred for an X-ray of the pelvis, right femur and right knee after complaints of migratory arthralgia in hip and knee five months after an initial hip and knee trauma. Bone lesions on X-ray were identified. This case report highlights the strength and complementary use of modern multimodality multiparametric imaging techniques in the clinical radiological manifestations of Erdheim-Chester disease, in the differential diagnosis and in treatment response assessment, which is classically performed using18FDG PET-CT. Erdheim-Chester disease is a rare form of non-Langerhans ...

Assessing tophaceous spinal gout treatment response using dual-energy CT as a point-of-care imaging modality: case report
We describe a case of chronic tophaceous gout affecting the spine, hands, elbows, feet, and knees in a 67-year-old man with serum urate levels at 549 µmol/L whose response to treatment was successfully mapped using dual-energy computed tomography (DECT). The patient presented with exacerbation of acute-on-chronic lumbar back pain. He had received a diagnosis of gout 3 years prior to this presentation yet was not on any urate-lowering therapy. The patient received febuxostat 80 mg and colchicine 0.3 mg once daily and underwent DECT to assess baseline monosodium urate (MSU) burden. At baseline, MSU deposits were seen i...

Edema-like marrow signal intensity (ELMSI) associated with nonossifying fibroma (NOF) on MRI: an uncommon finding in a common bone lesion
ConclusionELMSI can be seen about NOFs encountered around the knee joint on MRI, which may represent active healing and/or involutional change of this “do not touch” lesion in cases where no other explanation is identified. (Source: Skeletal Radiology)

Does the apparent diffusion coefficient from diffusion-weighted MRI imaging aid in the characterization of malignant soft tissue tumors and sarcomas
ConclusionDiffusion-weighted imaging generated ADC measurements are reproducible but currently offer limited insight in being able to differentiate among different malignant soft tissue tumor and sarcoma histologies. T1W and T2W signal characteristics also offer limited insight in differentiating between soft tissue malignancies. (Source: Skeletal Radiology)
