Comparison between fragmented QRS and Q waves in myocardial scar detection using myocardial perfusion single photon emission computed tomography.

Background: Accurate diagnosis of myocardial infarction (MI) is of paramount importance in patient management, which necessitates the development of efficient and accurate diagnostic methods. Q wave is not present in all patients with MI, and its prevalence is declining. Recently, fragmented QRS (fQRS) complex has been introduced as a marker of prior MI.

99mTc-Pertechnetate imaging for detection of ectopic gastric mucosa: a systematic review and meta-analysis of the pertinent literature.

Background And Aims: 99mTc-pertechnetate scintigraphy has long been used for detection of ectopic gastric mucosa (EGM) in the medical practice and evaluation of children with lower gastrointestinal bleeding. In the current study, we reviewed the available medical literature in this regard.

Methods: Medline and SCOPUS were searched for relevant studies.

Diagnostic value of 99mTc-bombesin scintigraphy for differentiation of malignant from benign breast lesions.

Objective: In this study, we evaluated the diagnostic accuracy of (99m)Tc-bombesin scintigraphy for differentiation of benign from malignant palpable breast lesions. (99m)Tc-Bombesin is a tracer with high affinity for gastrin-releasing peptide receptor, which is overexpressed on a variety of human tumors including breast carcinoma.

Materials And Methods: We examined 33 consecutive women who were referred to our center with suspicious palpable breast lesions but had no definitive diagnosis in other imaging procedures.

Isolated primary lymphedema tarda of the upper limb.

Primary lymphedema tarda is considered as a congenital disease with late presentation. Primary lymphedema tarda usually affects lower limbs, and primary lymphedema tarda of the upper limbs usually accompanies lower limb lymphedema. In the current case report, we present an 80-year-old male patient with isolated left upper limb swelling that lymphoscintigraphy imaging proved to be lymphedema.
