Whole-body bone scintigraphy (WBS) is one of the most widely used modalities in diagnosing malignant diseases during early stages. However, procedure time-consuming and requires vigour experience. Moreover, interpretation WBS scans stages disorders might be challenging because patterns often reflect normal appearance that prone to subjective interpretation. To simplify gruelling, subjective, prone-to-error task interpreting scans, we developed deep learning (DL) models automate two major...
Pyogenic granuloma is a benign, acquired, proliferative vascular lesion of the skin and mucous membranes. Many different treatments have been used for pyogenic with variable success rates.To evaluate efficacy cryotherapy in treatment granuloma.In prospective observational study, 135 patients were treated using liquid nitrogen. The followed up every 3 weeks until months after disappearance lesion.Complete resolution was achieved all mean 1.58 (range, 1-4 treatments). At end follow-up period,...
Fragmented QRS (FQRS) on surface electrocardiogram (ECG) is associated with the presence of myocardial scar tissue and may have prognostic value after certain ischemic events. We aimed to examine anatomical correlation FQRS perfusion abnormalities in patients suspected coronary artery disease (CAD).Patients without a known history CAD, who were referred for imaging (MPI) between January 2016 May 2016, enrolled. The ECG was evaluated. FQRS, number leads location as well patient...
Gastric cancer is one of the most common and fatal neoplasms in human. Its skeletal metastasis less frequent, particularly when solitary. The objective this article to represent a case solitary fibular from not reported before based on Medline search.
Early detection and monitoring of kidney function during the post-transplantation period is one most important issues for improving accuracy an initial diagnosis. The aim this study was to evaluate texture analysis (TA) in scintigraphic imaging detect changes status after transplantation.Scintigraphic images were used TA from a total 94 allografts (39 rejected 55 non-rejected). Images corresponding frames at 2nd, 5th, 20th minute determine optimum time point differences features between...
The technetium-99m ethylene dicysteine (Tc-99m EC) is a radiopharmaceutical used for renal scintigraphy, noninvasive imaging technique that assesses kidney function as well urinary tract obstruction. We describe the extrarenal Tc-99m EC uptake in 70-year-old man with recurrent well-differentiated abdominal liposarcoma. In present case, both liposarcoma lesions which were diagnosed by CT scan showed heterogeneous accumulation of EC.
Myocardial perfusion imaging (MPI) by 99mTc-sestamibi constitutes a major part of nuclear medicine studies. Incidental detection extracardiac abnormalities occurs not infrequently. These can include benign and malignant lesions their be great value in patient’s future. We present 60 year-old man who underwent MPI to evaluate coronary artery disease as the possible cause his chest discomfort. The images revealed large area intense increased tracer uptake antero- inferior mediastinum that...
The aim of our study was to compare the technetium-99m (Tc-99m)-ethylenedicysteine (EC) renography calculation differential renal function (DRF) with this measurement using Tc-99m-dimercaptosuccinic acid (DMSA) scintigraphy.Patients referred department were included in study, and both DMSA EC scans performed for each patient according standard imaging protocols. A checklist filled patient. Statistical analysis correlation regression methods.Forty-two patients (mean age: 3.6 ± 3.4 years),...
Background and Aim: Previous studies on heart response rate (HRR) were conducted in diabetic patients. This study aims to evaluate HRR end-stage renal disease (ESRD) patients its correlation with myocardial perfusion imaging (MPI) findings patients’ prognosis. Materials Methods: The present was chronic kidney (CKD) who visited Shahid Hasheminejad Hospital between October 1, 2011, September 30, 2019. Before the stress test, patient asked rest a supine position for 3 minutes while an...
