technetium-99m subtraction scanning

چکیده
Solitary parathyroid adenomas were correctly located before surgery in 20 out of 21 cases by using 20lmTl and 99mTc in a subtraction technique. The technique was not useful in identifying hyperplastic parathyroid glands. The technique is recommended as a useful procedure before surgery for primary hyperparathyroidism.

Radionuclide techniques in the diagnosis of primary hyperparathyroidism. The role of technetium 99m--thallium 201 subtraction scanning.
The role of various radionuclide investigations, including parathyroid scintigraphy, bone scintigraphy and serum parathormone estimations in the diagnosis of primary hyperparathyroidism is reviewed briefly. The initial experience with the dual isotope (Tl-201; Tc-99m) subtraction scintigraphy for the preoperative localization of parathyroid adenomas is presented (JPMA 37 : 237, 1987).
متن کاملUnilateral surgery for primary hyperparathyroidism on the basis of technetium Tc 99m sestamibi and iodine 123 subtraction scanning.
HYPOTHESIS Parathyroid scanning, based on simultaneous recording of technetium Tc 99m sestamibi and iodine 123 images, is able to identify patients with multiple parathyroid gland disease and is a safe imaging technique for unilateral parathyroid surgery. DESIGN Scintigraphic criteria of eligibility for unilateral surgery were prospectively tested against findings of conventional bilateral su...
متن کاملA five year audit of the role of parathyroid hormone assays and thallium-technetium isotope subtraction scanning
An audit has been performed of the value of parathyroid hormone assays and thallium-technetium isotope scanning in the pre-operative investigation of 67 hypercalcaemic patients referred for surgery over a 5 year period. Parathyroid hormone assay by region-specific technique was found to have a diagnostic sensitivity of75% (n = 52) whilst the more recent assay for the intact molecule was 97% sen...
متن کاملNuclide imaging of vascular graft-platelet interactions: comparison of indium excess and technetium subtraction techniques.
Indium-111-labeled platelet adherence to ePTFE thoracoabdominal vascular prostheses in a canine model (n = 10) was quantitated by (1) an indium-111 excess technique, contrasting graft radioactivity to that in a reference region, and (2) a technetium-99m subtraction technique, with radioactivity of circulating platelets eliminated by discounting background blood activity. Variation in graft thro...
متن کاملA comparison of 10 MHz ultrasound and 201-thallium/99m-technetium subtraction scanning in primary hyperparathyroidism.
Both high resolution (10 MHz) ultrasound and 201-thallium/99m-technetium subtraction scanning (Tl/Tc) were carried out preoperatively in 25 patients with primary hyperparathyroidism. Operative findings were the standard against which these two imaging methodologies were compared. Tl/Tc scanning showed a sensitivity of 42% and a specificity of 97%. By comparison, sensitivity of ultrasound was 38...
