A fistula is an unusual communication between the skin and an inward organ or between the organs. The current study aimed to determine the role of magnetic resonance imaging (MRI) in the diagnosis, description, and classification of fistula-in-ano. Additionally, the study aimed to compare the MRI findings with the operative findings, which is considered the gold standard in our study. The present study

mpMRI features of mucinous prostate cancer: two case reports Egypt. J. Radiol. Nucl. Med. (IF 0.7) Pub Date : 2024-07-22 Giuseppe Chiacchio, Alessandro Grimaldi, Edoardo Beatrici, Riccardo Rossi, Simone Cappuccelli, Lucia Pitoni, Vito Lacetera, Giuliana Gabrielloni, Alberto Rebonato, Simone Scarcella, Valerio Beatrici
Mucinous adenocarcinoma of the prostate (MACP) is one of the rarest variants of prostatic neoplasm, with more aggressive behavior than non-mucinous prostatic cancer. Previous studies suggested that these tumors exhibit different imaging magnetic resonance imaging (MRI) features compared with those of non-mucinous adenocarcinoma of the prostate upon which the conventional PIRADS v2.1 is based. To the

F-18 FDG PET/CT scan in recurrent prosthetic valve endocarditis without detectable abnormality on echo: a case report Egypt. J. Radiol. Nucl. Med. (IF 0.7) Pub Date : 2024-07-22 Nurnadiah A. Denil, Reana D. Arunasalem, Siti Zarina Amir Hassan
Infective endocarditis poses many clinical and diagnostic challenge. The diagnosis of infective endocarditis is made by high index of clinical suspicion based on the American Heart Association modified Duke’s criteria, and the main imaging modality of choice is echocardiography. Here, we reported a case of recurrent infective endocarditis revealed by FDG PET/CT study despite completion of antibiotics

Predictive quantitative multidetector computed tomography models for characterization of renal cell carcinoma subtypes and differentiation from renal oncocytoma: nomogram algorithmic approach analysis Egypt. J. Radiol. Nucl. Med. (IF 0.7) Pub Date : 2024-07-11 Haytham Shebel, Heba M. Abou El Atta, Tarek El-Diasty, Doaa Elsayed Sharaf
Our objective is to develop an algorithmic approach using predictive models to discriminate between common solid renal masses, including renal cell carcinoma [RCC] subtypes and renal oncocytoma [RO], using multiphase computed tomography [CT]. We retrospectively analyzed a group of solid renal masses between January 2011 and January 2023 regarding the CT attenuation values using a multiphase multidetector

Mitochondrial neurogastrointestinal encephalopathy: a case report Egypt. J. Radiol. Nucl. Med. (IF 0.7) Pub Date : 2024-07-09 Ghazaleh Jamalipour Soufi, Ali Hekmatnia, Farzaneh Hekmatnia, Andrew Parviz Zarei, Farshad Riahi, Shamim Shafieyoon, Sara Azizollahi
Mitochondrial neurogastrointestinal encephalopathy (MNGIE) is an autosomal recessive disease associated with alterations in mitochondrial DNA (mtDNA). The typical age of onset of MNGIE is between the first and second decade of life. Diagnosis requires the presence of several key clinical features: sensorimotor neuropathy, external ophthalmoplegia, ocular ptosis, leukoencephalopathy, and gastrointestinal

Reduction of myocardial lipid content assessed by H1 magnetic resonance spectroscopy in dyslipidemic patients after statins Egypt. J. Radiol. Nucl. Med. (IF 0.7) Pub Date : 2024-07-09 Eslam Elsayed Mohamed Elmenyawy, Hend Gamal Abu-El Fadl, Hesham Mohammed Fathy Waly, Abdul Razek Abdul Lateef Maaty, Hanaa Mahmoud Mohammad Abdelaziz
Dyslipidemia is one of the main modifiable risk factors for cardiovascular diseases, which accounts for one third of total deaths worldwide. Statin is considered the cornerstone therapy for treating dyslipidemic patients. H1 Cardiac magnetic resonance spectroscopy (MRS) is a special non-invasive, non-irradiating method for assessing myocardial lipid content in vivo in both health and disease. To compare

Inter-observer and inter-modality concordance of non-contrast MR angiography and CT angiography for preoperative assessment of potential renal donors Egypt. J. Radiol. Nucl. Med. (IF 0.7) Pub Date : 2024-07-09 Ali H. Elmokadem, Mohamed A. Ouda, Talal Amer, Tarek A. El-Diasty, Mona Zaki
Magnetic resonance angiography (MRA) is rapidly being employed as an effective substitute for CTA, particularly in situations of poor kidney function. We aimed to examine the inter-observer and inter-modality reliability of non-contrast MR angiography (NC-MRA) and CTA as a non-invasive tool for assessing the anatomical findings of potential living kidney donors. All potential donors were referred from

Comparing early and delayed [99mTc]Tc-MIBI SPECT/CT parathyroid scans: agreement, confidence levels, and clinical predictive factors Egypt. J. Radiol. Nucl. Med. (IF 0.7) Pub Date : 2024-07-09 Chanittha Buakhao, Sira Vachatimanont
Parathyroid scan is an important imaging modality for localizing hyperfunctioning parathyroid tissue in patients with hyperparathyroidism. Unfortunately, whether early or delayed timing is the optimal protocol for [99mTc]Tc-MIBI SPECT/CT parathyroid remains under debate. This study aimed to evaluate the agreement and compare the confidence levels of physicians when interpreting early and delayed [99mTc]Tc-MIBI

MR imaging of endolymphatic hydrops in Ménière’s disease: feasibility at 1.5 T Egypt. J. Radiol. Nucl. Med. (IF 0.7) Pub Date : 2024-07-08 Amine Ben Lakhal, Seif Boukriba, Rim Bechraoui, Sondes Mannoubi, Habiba Mizouni
Ménière’s disease is a chronic condition of the inner ear that causes vertigo, tinnitus and hearing loss. Its diagnosis relies on clinical criteria that are subjective and pure-tone audiometry results that are not specific. Its pathological substrate is endolymphatic hydrops. Its imaging was recently made possible by the late-enhanced 3D FLAIR sequence. This technique was primarily tested on 3 T. Our

Transarterial embolization in Wunderlich syndrome due to recanalization of giant renal angiomyolipoma pseudoaneurysm: a case report and literature review Egypt. J. Radiol. Nucl. Med. (IF 0.7) Pub Date : 2024-07-05 Koesbandono, Prijo Sidipratomo, Raditya Utomo, Christiano Tansol, Yohanes Chandra Kurniawan
Acute spontaneous bleeding from renal angiomyolipoma (AML) is one of the causes of Wunderlich syndrome, a rare and potentially fatal clinical condition. Clinical deterioration will occur if there is a delay in urgent management. There are several management options for renal angiomyolipoma rupture. However, until now little is known about the case of recanalization from post-coil embolization of renal

Value of digital breast tomosynthesis in characterization of breast lesions in dense breast Egypt. J. Radiol. Nucl. Med. (IF 0.7) Pub Date : 2024-07-03 Marwa Romeih, Tarek Ahmed Raafat, Gehad Ahmed, Shymaa Abd El-Mawla Shalaby, Wafaa Ali Heidar Ahmed
Patients with dense breasts have a higher risk factor for developing breast cancer. Digital mammography (DM) exhibits a reduced sensitivity in dense breast tissue as a result of overlapping fibro-glandular tissue. Digital breast tomosynthesis (DBT) solves this problem, so allows better characterization of masses, asymmetries, and parenchymal distortion. It is useful in screening studies for early detection

Prospective evaluation of the diagnostic efficacy of multiparametric MRI clear cell Likelihood Score in small solid renal masses and its predictive value for tumor grade Egypt. J. Radiol. Nucl. Med. (IF 0.7) Pub Date : 2024-07-02 Osama M. Soliman, Amani Ezzat Mousa, Mona Zaky, Abdalla Abdelhamid
The detection of small renal masses has significantly increased due to the widespread use of cross-sectional imaging in recent years. Among these masses, clear cell renal cell carcinoma (ccRCC) is the most common subtype and progresses quickly, resulting in the advancement of the disease and the development of metastases. In this prospective study, our goal is to assess the effectiveness of multiparametric
