“…Hence, the field of nuclear medicine is governed by the principle of ALARA. 5 In this regard, the American Society of Nuclear Cardiology in 2010 had set a target of achieving <9mSv effective dose in at least 50% of the studies by 2014. 6 However, INCAPS worldwide survey (2013) showed an effective dose ranging from <5 to >18 mSV with only 30% laboratories achieving the goal of <9mSv.…”

“…These include low dose radiopharmaceuticals and stress-only imaging, where applicable. Omitting the rest scan not only saves time and cost, 5 but also reduces radiation exposure by 80%. 7 The usefulness of stress-only MPI has been confirmed by many large study groups, in whom stress-only protocol showed a good prognosis in patients with normal stress perfusion.…”

Objective: To validate ‘stress only’ protocol against ‘rest stress protocol in normal and essentially normal cases undergoing Tc99m MIBI gated myocardial perfusion Single Photon Emission Computed Tomography imaging. Study Design: A retrospective observational study. Place and Duration of Study: Department of Nuclear Cardiology, Armed Forces Institute of Cardiology/National Institute of Heart Disease, Rawalpindi, Pakistan, from Jul to Sep 2019. Methodology: 136 cases were included. Patients underwent Tc-99m gated Single Photon Emission Computed Tomography MPI using a single day, rest/stress protocol. The rest study was performed first with 8-10 mCi Tc-99m MIBI followed by stress study, 3 hours later with 3 times the rest dose. The most common stress technique was pharmacological stress and bicycle ergometer exercise with 0.14 mg/kg/min adenosine infusion. Few patients underwent physical stress using Bruce protocol, achieving a minimum of 85% of the target heart rate. Mages–stress followed by rest–were evaluated by two experienced nuclear cardiologists (blinded to the MPI reports) and interpreted as ‘normal’ or ‘essentially normal’. Results: Evaluation of stress-only and rest-stress Single Photon Emission Computed Tomography myocardial images yielded a concordance rate of 84.56% with Cohen’s kappa coefficient of 0.69. Conclusion: Substantial agreement and good concordance were found in normal and essentially normal ‘stress only’ and ‘rest stress protocols.

Introduction: To date, there are few reports on computed tomography angiography (CTA) in combination with stress myocardial perfusion imaging (SMPI) in the diagnosis of coronary slow flow (CSF). Methods: A total of 62 patients with suspected CSF who were scheduled to undergo CTA, SMPI and coronary angiography (CAG) from June 2019 to June 2021 were selected. With the results of CAG as the gold standard, the value of CTA plus SMPI in the diagnosis of CSF was analyzed. Results: Of the 62 patients, 52 (83.87%) were diagnosed with CSF by CAG. The results of the Kappa consistency test showed that SMPI alone, CTA alone and SMPI plus CTA had 0.565, 0.396 and 0.881 consistency, respectively, with CAG in the diagnosis of CSF. The sensitivity, specificity, accuracy, positive predictive value and negative predictive value of SMPI plus CTA in the diagnosis of CSF were 98.08% (51/52), 90.00% (9/10), 96.47% (60/62), 98.08% (51/52), and 90.00% (9/10), respectively, all higher than those of SMPI or CTA alone (P<0.05). The areas under the receiver operating characteristic curves of SMPI alone, CTA alone and SMPI plus CTA in the diagnosis of CSF were 0.754, 0.771 and 0.940, respectively. Conclusion: CTA and SMPI have high diagnostic values for CSF, and the results of their combination have high consistency with those of CAG.
