Succinate dehydrogenase mutations: paraganglioma imaging and at-risk population screening.

Paragangliomas are rare vascular tumours of the autonomic nervous system. They can be classified as sympathetic or parasympathetic. Sympathetic paragangliomas, which include phaeochromocytomas, tend to be functional and symptomatic.

SPECT/CT-Guided Ultrasound for Parathyroid Adenoma Localization: A 1-Stop Approach.

Our rationale was to evaluate the accuracy of 1-stop (single patient-attendance) SPECT/CT-guided ultrasound in the localization of parathyroid adenomata. Secondary aims included analyzing the effect of multiple parathyroid adenomata and concurrent thyroid disease on sensitivity. Patients with hyperparathyroidism who had undergone parathyroidectomy were identified over a 5-y period.

MRI ankle and subtalar characteristics in haemochromatosis arthropathy: a case-control study.

Aim: To examine the magnetic resonance imaging (MRI) features of the ankle and subtalar joints that might distinguish genetic haemochromatosis (GH).

Materials And Methods: The present study was a retrospective case-control study comparing 30 MRI studies of GH patients with ankle or subtalar arthropathy with 30 matched controls with ankle pain. Anonymised images were scored using a semi-quantative tool adapted from the MRI osteoarthritis knee score.

Diagnostic modalities.

The incidental detection of small renal masses on imaging undertaken to evaluate unrelated symptoms or conditions is an increasingly common occurrence. Accurate imaging characterisation is fundamental to determining optimum patient management. The goals of imaging small renal masses include determining whether a lesion is solid or cystic, if there are signs of biological aggressiveness and whether the lesion is likely benign or malignant.
