Genicular Nerve Block for Pain Management in Patients With Knee Osteoarthritis: A Randomized Placebo-Controlled Trial.

Objective: This study was undertaken to determine the efficacy of ultrasound-guided genicular nerve block (GNB) for the management of knee pain in patients with knee osteoarthritis.

Methods: We performed a 12-week parallel-group, placebo-controlled randomized trial of GNB. Within 2 weeks of randomization, patients with knee osteoarthritis in the active arm received 3 injections of 5.

The retrodural space of Okada and its relevance to CT guided intervention.

The spinal epidural and posterior ligamentous complex spaces are important anatomic regions which are the target of various radiologic procedures in the cervical, thoracic and lumbar spine for the purpose of analgesia and anaesthesia. Given the frequency with which procedures are performed in and around the epidural space, a sound understanding of the associated anatomy is paramount to ensure the safety and efficacy of procedural intervention.

Transient uterine contractions as a potential pathology mimic on premenopausal pelvic MRI and the role of routine repeat T2 sagittal images to improve observer confidence.

Introduction: Pelvic MRI has an increasingly important role in the evaluation of non-malignant uterine pathology including uterine leiomyomas, adenomyosis and endometriosis. Normal physiological myometrial junctional zone transient contractions can also be identified on MRI and have the potential to act as pathology mimics. This study aims to evaluate both the incidence of visible physiological contractions in premenopausal female pelvic MRI and also to support the routine acquisition of a repeat T2 sagittal sequence to differentiate transient physiological contractions from true underlying pathology and therefore improve observer confidence.

Intravenous lobular capillary haemangioma (pyogenic granuloma): A case report and a review of imaging findings as reported in the literature.

Introduction: Intravenous lobular capillary haemangioma (IVLCH) is a rare benign lesion with minimal published reports containing a description of its appearance at medical imaging. We present the ultrasound and MRI images of a histologically proven IVLCH and provide the first review of the imaging findings reported in the literature.

Methods: The imaging findings of a case of IVLCH are presented.

Imaging of the symptomatic type II accessory navicular bone.

Accessory ossicles of the foot are commonly mistaken for fractures. The accessory navicular is one of the most common accessory ossicles of the foot. There is a higher incidence in women and the finding might be bilateral in 50-90%.

Spontaneous extraperitoneal haemorrhage: computed tomography diagnosis and treatment by selective arterial embolization.

Four cases of extraperitoneal haemorrhage occurring in the setting of anticoagulation or coagulopathy are presented. Treatment of this condition has traditionally consisted of reversal of anticoagulation and supportive therapy. Diagnosis was made on contrast-enhanced computed tomography.

Endosonographic imaging of anal sphincter injury: does the size of the tear correlate with the degree of dysfunction?

Purpose: This study was designed to test the hypothesis that the extent of anal sphincter muscle injury as graded at endosonography correlates with the degree of functional impairment.

Methods: Three hundred and thirty adults presenting for evaluation of fecal incontinence were recruited. Ultrasound was performed with a 7.

Radiographic imaging procedures in the diagnosis of the major central neuropathological consequences of alcohol abuse.

Excessive consumption of alcohol is well recognized to have specific neurologic sequelae. The MRI and CT findings in these syndromes is presented and correlated with pathological findings and suspected pathogenesis. The role of imaging in both the diagnosis and monitoring of patients is discussed.
