Abstract:

Purpose: With  increasing the usage  of  myocardial  perfusion  imaging  (MPI)  for  the diagnosis  of  ischemic  heart  disease,  we  aimed  to  evaluate  the  side  effects  of  low-dose  radiation  induced  by  this  technique  on blood elements, especially proteins and liver function factors.Materials and  Methods:  40  eligible  patients  (Mean  age:  54.62±10.35,  22 female  and  18  male),  who  had  referred  to  the  nuclear  medicine  department  for  MPI  from  May  till  August  2014,  were  enrolled  in  the  study.  A blood  sample  was  taken  from  each  patient  just  before  and  24  hours  after  the injection  of  740Mbq  of  Tecnetium-99m  Methoxy  isobutyl  isonitrile  (99mTc-MIBI)  in  the  rest  phase  of  the  MPI  in  a  reference  medical  laboratory; blood  tests  included  total  protein  (TP),  albumin  (Alb),  globulin  (Glo),  aspartate  aminotransferase  (AST),  alanine  transaminase(ALT),  alkaline  phosphatase  (ALP),  direct  bilirubin  (D.Bili),  total  bilirubin  (T.Bili),serum  iron  (SI),  total  iron  bounding  capacity  (TIBC), Albumin  globulin  ratioA/G  ratio),  and  complete  blood  count  (CBC).Results:  Injection  of  740Mbq99mTc-MIBI  caused  a  significant  increase  in  serum  levels  of  AST  (p=  0.001),  ALT  (p=  0.001),  SI(p=  0.030),  TIBC  (p=  0.003)  and  A/G  Ratio  (p=  0.020). However,  following  radiotracer injection,  a  significant  decrease  was  noted  in  the  serum  levels  of  TP  (p=  0.002),  Alb  (p=  0.014),  Glo(p=  0.002),  ALP(p=  0.001),  D.Bili  (p=  0.003)  and  T.Bili(p=  0.000).Conclusion: Due  to  increased  usage  of  MPI, our  data  highlights  the  importance  of  monitoring  the  clinical  and  paraclinical  effects  of  the  procedure  on  vital  organs  and  physiological  pathways  to  reduce  their  adverse  effects.

Radiation-induced myocardial perfusion abnormalities in breast cancer patients following external beam radiation therapy

Objective(s): Radiation therapy for breast cancer can induce myocardial capillary injury and increase cardiovascular morbidity and mortality. A prospective cohort was conducted to study the prevalence of myocardial perfusion abnormalities following radiation therapy of left-sided breast cancer patients as compared to those with right–sided cancer. Methods: To minimize potential confounding fact...

Approaches to reducing radiation dose from radionuclide myocardial perfusion imaging.

Radionuclide myocardial perfusion imaging (MPI) plays a vital role in the evaluation and management of patients with coronary artery disease. However, because of a steep growth in MPI in the mid 2000s, concerns about inappropriate use of MPI and imaging-related radiation exposure increased. In response, the professional societies developed appropriate-use criteria for MPI. Simultaneously, novel...

Evaluating the Effect of Injected Dose of 99mTc- MIBI on the Quantitative Parameters of Myocardial Perfusion Imaging

Background: 99mTc-MIBI cardiac perfusion scanning is recognized as a clinically useful method in evaluating coronary artery disease. By the implementation of new imaging techniques and systems, it seems possible to obtain high-quality images with a lower dose of radiopharmaceuticals. The purpose of this study was to evaluate the effect of injection dose of 99mTc-MIBI on quantitative parameters ...

Evaluation of myocardial perfusion and function after kidney transplantation by Gated SPECT myocardial perfusion scintigraphy

Introduction: The aim of this study was to evaluate the effect of successful kidney transplantation (KT) on myocardial perfusion and left ventricular function by both qualitative (visual) interpretation and semiquantitative parameters, using myocardial perfusion scintigraphy with gated-single photon emission computed tomography (gated-SPECT) in patients suffering from end-stage renal disease. ...

Low radiation dose imaging of myocardial perfusion and coronary angiography with a hybrid PET/CT scanner

OBJECTIVES To test the image quality and feasibility of a sequential low radiation dose protocol for hybrid cardiac PET/CT angiography (CTA). BACKGROUND Multidetector computed tomography (MDCT) is a non-invasive method for coronary angiography. The negative predictive value of MDCT is high but perfusion imaging has a role in detecting functional significance of coronary lesions. This has enco...
