The various bio imaging techniques provides a non invasive method to monitor the in vivo fate of the different pharmaceutical formulations post administration into the body. The different imaging techniques including gamma scintigraphy, near infra red fluorescent dyes helps to predict the pharmacokinetic behaviour of dosage form in subjects under investigation. The transit of dosage form throug...

Correlation and concordance of glomerular filtration rate from renal scintigraphy modified modification diet in disease equation

INTRODUCTION The treatment of primary hyperparathyroidism consists almost exclusively in the parathyroidectomy. The preoperative imaging (ultrasonography, 99mTc sestamibi scan) can allow to localize the pathologic gland and perform minimally-invasive focused techniques, but in presence of ectopic or intrathyroidal glands, parathyroid hyperplasia or coexistent thyroid disease, the sensitivity of...

We looked into the problem that the quantitative values of 123I data vary according to collimator type. First, we made the assumption that the quantitative values of 123I data are degraded by the scattered photons from the 529 keV component which contaminate the 159 keV imaging data. Then, the 123I Dual Window (IDW) method was proposed to improve the quantitative values of the 123I data. The ID...

Introduction: Appendicitis is one of the most common surgical emergencies. In spite of the relatively high rate of negative appendectomy, as a result of miss diagnosis, uncertainty of diagnosis still continues to challenge physicians. The objective of this prospective study was to investigate the role of 99mTc-Ubiquicidin (UBI) scintigraphy in the diagnosis of acute appendicitis and ...

Planar lung ventilation/perfusion scintigraphy (V/P(PLANAR)) is a standard method for diagnosis of pulmonary embolism (PE). The goals of this study were to test whether the diagnostic information of ventilation/perfusion tomography (V/P(SPET)) applied in clinical routine might enhance information compared with V/P(PLANAR) and to streamline data processing for the demands of clinical routine. Th...

Measurement of colon transit time is the most basic and primary tool in evaluating disorders of colonic motility. In particular, it is helpful in pathologic diagnosis and for planning management in patients with constipation. Several techniques for measuring colon transit time currently exist. The standard measurement of colon transit time has been performed using radioopaque marker test. The r...

UNLABELLED The purpose of this prospective study was to assess the role of SPECT/multislice low-dose (Msl) CT as a constituent in the imaging algorithm of nononcologic patients referred for 99mTc-methylene diphosphonate bone scintigraphy (BS). METHODS SPECT/CT was performed using a novel hybrid system, which incorporates a gamma-camera and a multislice low-dose CT, on 76 consecutive nononcolo...

Background. A proper localisation of pathological parathyroid glands is essential for a minimally invasive approach in the surgical treatment of primary hyperparathyroidism (PHP). The recent introduction of portable mini gamma-cameras (pMGCs) enabled intraoperative scintigraphic scanning. The aim of our study is to evaluate the efficacy of this new method and compare it with the preoperative lo...

Technetium-99m-diethylenetriaminepentaacetic acid-galactosyl-human serum albumin (99mTc-GSA) is a liver scintigraphy agent which binds to asialoglycoprotein receptor in hepatocyte. Twenty-six patients with liver dysfunction were examined with 99mTc-GSA liver scintigraphy using two-compartment and two-parameter model (2C2P model). The 99mTc-GSA was assumed to move within two compartments (whole ...
