INTRODUCTION The aim of this study was to assess the utility of [Lys40(Ahx-HYNIC-99mTc/EDDA)NH2]-exendin-4 scintigraphy in the management of patients with hypoglycemia, particularly in the detection of occult insulinoma. MATERIALS AND METHODS Forty patients with hypoglycemia and increased/confusing results of serum insulin and C-peptide concentration and negative/inconclusive results of other...
We recently stored a 1.85 GeV/c vertically polarized deuteron beam in the COSY Ring in Jtilich; we then spin-flipped it by ramping a new air-core rf dipole's frequency through an rfinduced spin resonance to manipulate the polarization direction of the deuteron beam. We first experimentally determined the resonance's frequency and set the dipole's rf voltage to its maximum; then we varied its fr...
RATIONALE AND OBJECTIVES To evaluate the impact of computer-aided detection (CAD, IQQA-Chest; EDDA Technology, Princeton Junction, NJ) used as second reader on the detection of small pulmonary nodules in chest radiography (CXR). MATERIALS AND METHODS A total of 113 patients (mean age 62 years) with CT and CXR within 6 weeks were selected. Fifty-nine patients showed 101 pulmonary nodules (diam...
the kinetics of the de complexation by hydroxyl ions of some pervanadyl, molybdate and tungstate amionocarboxylate complexes have been studied spectrophotometrically by means of a stopped flow technique. the chelate groups used were the iminodiacetic acid (ida), ethylenediarnine-n,n' -diacetic acid (edda), nitrilotriacetic acid (nta) and ethylene diamine-n,n,n' ,n'-tetraacetic ac...
background: bombesin shows high affinity for gastrin-releasing peptide (grp) receptors which over expressed on the cell surfaces of several human tumors particularly in prostate and breast cancers. the aim of this study was labeling of designed analogue with99mtc via hynic and tricine /edda and evaluation as potential targeted tumor scintigraphic agent.materials and methods: hynic-bombesin was ...
context inherited and sporadic medullary thyroid cancer (mtc) is an uncommon and medically challenging malignancy. even if the extent of initial surgery is deemed adequate, the recurrence rate remains high, up to 50% in most series. measurement of serum calcitonin is important in the follow-up of patients with mtc, and reliably reflects the existence of the disease. evidence acquisition there i...
Neurokinin 1 receptors (NK1R) are overexpressed on several types of important human cancer cells. Substance P (SP) is the most specific endogenous ligand known for NK1Rs. Accordingly, a new SP analogue was synthesized and evaluated for detection of NK1R positive tumors. [6-hydrazinopyridine-3-carboxylic acid (HYNIC)-Tyr8-Met(O)11-SP] was synthesized and radiolabeled with 99mTc using ethylenedia...
