Radioiodine ablation – current trends and controversies

Management for differentiated thyroid cancer (DTC) has seen significant changes over the last decade. The approach is dramatically shifting to personalised based rational decisions. This includes, but is not limited to, the extent of surgery, active surveillance in low risk very limited disease, radioiodine (RAI) ablation or no ablation after initial surgery, low iodine activity […]

Hobnail papillary thyroid carcinoma: clinical and sonographic findings of a rare tumour

Thyroid cancer represents one of the most common malignancies worldwide, accounting for 1% of cancer diagnoses. Papillary thyroid carcinoma (PTC) is the most common subtype, representing approximately 80% of thyroid cancer cases. PTCs generally have a good prognosis, with a survival rate of >95% over five years. The reported incidence of PTC has been increasing […]

SPECT/CT in oncology

Radionuclide imaging can demonstrate whole body functional/metabolic information and plays an important role in oncology clinical and research practice. It is integral to many clinical pathways, assisting in diagnosis and staging, pre-operative localisation, monitoring response and detecting recurrence. However, planar scintigraphy and SPECT lack anatomical and structural details resulting in low specificity and sensitivity with […]

Ultrasound thyroid nodule evaluation

Ultrasound examination is the most frequently used method to assess thyroid gland abnormalities by radiologists and sonographers, due to the close proximity of the thyroid tissue to the skin and the excellent images obtained using high frequency ultrasound transducers and optimised image reconstruction algorithms on current ultrasound machines.

The new ACR TI-RADs: A step towards a risk stratified approach to thyroid FNA?

Thyroid nodules are very common: 4-8% of the general population have palpable nodules while 19-67% will have nodules sonographically. The vast majority of these thyroid nodules are benign with only a minority (2-12%) being malignant. The increasing use of sonography has resulted in what is often referred to as a “thyroid storm”. However, despite this […]

The role of nuclear medicine imaging in the diagnosis of hyperparathyroidism

There are four parathyroid glands, two on each side, weighing around 20-40mg, located in the neck along the posterior aspect of the thyroid gland. Occasionally, there may be five or six parathyroid glands in the neck or an ectopic gland, located most commonly within the chest. The superior parathyroid glands are most commonly located on […]
