As the SPECT and SPECT-CT codes were being re-vamped, there are a couple that are not impacted by the change: myocardial perfusion and parathyroid imaging have retained their site-specific SPECT codes. Continue to report these as usual. parathyroid glands in patients with documented hyperparathyroidism. It is particularly helpful in patients who have persistent or recurrent hyperparathyroidism after parathyroidectomy. SPECT/CT is most useful in patients with prior neck surgery or in patients where the initial planar images show a possible parathyroid adenoma in an ectopic 1 SPECT/CT in Parathyroid Disease Ann-Marie Quigley Nuclear Medicine Royal Free Hospital London Outline Pathophysiology Current guidelines SPECT/CT – the evidence SPECT/CT in clinical scenarios The successful registration of SPECT with CT for localization purposes may aid definitive diagnosis and provide more precise lesion localization as part of surgical work-up for parathyroid adenomas. The parathyroid glands are small lentil-shaped glands that generally are located adjacent to the thyroid gland. Parathyroid scintigraphy has proven to be the single best imaging modality for preoperative localization of parathyroid adenomas, that is, superior to ultrasonography, CT, and MRI (6 – 8).

Both sensitivity and specificity were higher with combined SPECT/CT with pinhole than with SPECT/CT alone (97% versus 94% and 99% versus 98%, resp., not significant). SPECT/CT fusion imaging is increasing used, due to the three-dimensional information, it provides and the improved sensitivity for the detection and localization of hyperfunctioning parathyroid lesions. SPECT/CT can further enhance localization by providing better resolution of surrounding structures and has the added benefit of a more precise Clinical utility of ultrasound and 99mTc sestamibi SPECT/CT for preoperative localization of parathyroid adenoma in patients with primary hyperparathyroidism.

We aimed to assess the added value of dual isotope subtraction SPECT/CT over single isotope SPECT/CT as an adjunct to dual isotope planar pinhole subtraction scintigraphy.

2011-07-27 · Primary hyperparathyroidism is caused by a single parathyroid adenoma in up to 90% of clinical cases. Selective surgical excision of the hyperfunctioning parathyroid gland is the treatment of choice for this condition, and parathyroid scintigraphy is one of the primary and standard methods used for preoperative localization. SPECT/CT is advantageous over planar imaging because SPECT/CT Planar (dual phase) and delayed SPECT/CT Surgical confirmation: 35 parathyroid adenomas/hyperplasia (all eutopic) Lesion by lesion: SPECT/CT detected 8 (23%) more lesions than SPECT alone and 11 more than planar SPECT/CT also correctly localised them (quadrant) Kim et al, Ann Nucl Med 2012; 26:804-810 Localization of Hyperfunctioning Parathyroid Glands. SPECT/CT allows three-dimensional (lateral, supero-inferior, and anteroposterior) localization of the parathyroid glands. Lateral localization may be described as right, left, or midline (, Figs 5,,, , 6,,).

Question: We are doing planar and SPECT imaging of parathyroids. Should we use the parathyroid CPT view or SPECT) (Fig. 1). Imaging should identify ectopic glands (add. SPECT in cases of a mediastinal focus, and ask for additional CT or MRI for confirmation. To investigate how your parathyroid glands are functioning you will have to attend the hospital for two scans over two days: • Day 1: SPECT CT Parathyroid Scan. parathyroid SPECT-CT were included for this study.
SPECT/CT imaging with complementary anatomic and functional mapping has special applicability in parathyroid scintigraphy. On SPECT/CT (► Fig. 4.2), the low-resolution CT of the SPECT/CT shows that most of the thyroid nodules have no iodine uptake.
