Nodular lymphoid hyperplasia of terminal ileum: how to avoid overdiagnosis of Crohn ’s terminal ileitis in MR enterography?
AbstractPurposeTo investigate the magnetic resonance enterography (MRE) characteristics of nodular lymphoid hyperplasia (NLH) and Crohn ’s terminal ileitis (CTI).MethodsOf 1552 MREs from November 2011 to July 2018, 61 individuals with biopsy-proven NLH (n = 24) and CTI (n = 37, 27 with active CTI) were selected based on the inclusion criteria. NLH cases were also followed up for median (range) of 40 (21–61) months. Two board-certified radiologists, blind to clinical data and diagnosis, reviewed MRE in consensus. Conventional, morphological, enhancement, and di ffusion parameters were...

The evaluation of the use of 2D shear-wave ultrasound elastography in differentiation of clinically insignificant and significant liver fibrosis in pediatric age group
AbstractObjectiveTo determine the accuracy of 2D shear-wave elastography (2D-SWE) in pediatric age group patients in differentiating clinically insignificant and significant liver fibrosis using METAVIR fibrosis scoring system as the gold standard.IntroductionLiver biopsy has long been the gold standard in liver fibrosis diagnosis. However, due to probable complications and sampling variabilities, the need for more accurate and non-invasive techniques has increased. 2D-SWE is a non-invasive technique used in the evaluation of liver stiffness and utilized more and more in routine clinical practice with recent advances and r...

Mesenteric ischemia: a radiologic perspective
AbstractMesenteric ischemia is a broad term encompassing several clinical conditions leading to impaired vascularity of bowel loops. Absence of specific clinical presentation and a definitive laboratory marker often lead to delayed diagnosis with high morbidity and mortality in the acute setting. Imaging plays a crucial role in the diagnosis and management. Multi-detector CT (MDCT) is the first line imaging modality for the evaluation of patients with suspected mesenteric ischemia and plays an important role for assessing its severity and complications. This review article highlights the causes, pathophysiology, imaging fe...

Urinary collecting system invasion on multiphasic CT in renal cell carcinomas: prevalence, characteristics, and clinical significance
ConclusionThis study found that the prevalence of RCC-related CSI was 3%. Because of the low prevalence, we cannot exclude the possibility that CSI on CT would be associated with the OS and RFS. Further studies are needed to determine whether CSI on CT can be an independent prognostic factor for survival in patients with RCC. (Source: Abdominal Imaging)

Diagnostic performance of PET/CT and PET/MR in the management of ovarian carcinoma —a literature review
AbstractOvarian cancer is a challenging disease. It often presents at an advanced stage with frequent recurrence despite optimal management. Accurate staging and restaging are critical for improving treatment outcomes and determining the prognosis. Imaging is an indispensable component of ovarian cancer management. Hybrid imaging modalities, including positron emission tomography/computed tomography (PET/CT) and PET/magnetic resonance imaging (MRI), are emerging as potential non-invasive imaging tools for improved management of ovarian cancer. This review article discusses the role of PET/CT and PET/MRI in ovarian cancer. ...

Radiomics and radiogenomics in ovarian cancer: a literature review
AbstractOvarian cancer remains one of the most lethal gynecological cancers in the world despite extensive progress in the areas of chemotherapy and surgery. Many studies have postulated that this is because of the profound heterogeneity that underpins response to therapy and prognosis. Standard imaging evaluation using CT or MRI does not take into account this tumoral heterogeneity especially in advanced stages with peritoneal carcinomatosis. As such, newly emergent fields in the assessment of tumor heterogeneity have been proposed using radiomics to evaluate the whole tumor burden heterogeneity as opposed to single biops...

AbstractMucormycosis is a fungal infection caused by fungi of order mucorales. It is most commonly seen in patients with an impaired immune system due to any cause. Gastrointestinal mucormycosis is the least frequent type and may be a primary disease or a feature of generalized mucormycosis. Angioinvasion is the hallmark feature of mucormycosis, leading to bowel infarction which is the responsible for the most common clinical complaint of pain, and is also responsible for most of the imaging findings in this disease. The stomach is most commonly involved organ in the gastrointestinal tract and pneumatosis and lack of gastr...

Non-occlusive hepatic artery hypoperfusion syndrome and imaging findings: a systematic review
AbstractNon-occlusive hepatic artery hypoperfusion syndrome (NHAHS), in other words, splenic steal, is a rare disorder that can arise following liver transplantation.  After liver transplantation, its frequency has been defined as between 0.6 and 10.1%. The diversion of flow from hepatic to splenic arteries results in low perfused hepatic artery which causes elevated liver enzymes, hyperbilirubinemia, and graft dysfunction. This may result from a high resistance in the hepatic arteries, enlarged splenic arteries, a limited hepatic arterial flow due to high portal flow, or a discordance of the graft size and hepatic ar...

MR imaging assessment and quantification of liver iron
AbstractIron overload is a common clinical problem resulting from hereditary hemochromatosis or secondary hemosiderosis (mainly associated with transfusion therapy), being also associated with chronic liver diseases and metabolic disorders. Excess of iron accumulates in organs like the liver, pancreas and heart. Without treatment, patients with iron overload disorders will develop liver cirrhosis, diabetes and cardiomyopathy. Iron quantification is therefore crucial not only for diagnosis of iron overload but also to monitor iron-reducing therapies. Liver iron concentration is considered the surrogate marker of total body ...
