Imaging and Management of Rectal Cancer
Publication date: Available online 24 January 2020Source: Seminars in Ultrasound, CT and MRIAuthor(s): Supreeta Arya, Saugata Sen, Reena Engineer, Avanish Saklani, Tarun PandeyAbstractHigh-resolution phased array external MRI is the first investigation of choice in rectal cancer for local staging, both in the primary and restaging situations. Use of MRI helps differentiate between those with good prognosis, which can be offered upfront surgery and the poor prognostic cases where treatment intensification is needed. MRI identified poor prognostic factors are threatened or involved mesorectal fascia, T3 tumors with> 5mm extr...

Imaging and Management of Liver Cancer
Publication date: Available online 14 December 2019Source: Seminars in Ultrasound, CT and MRIAuthor(s): Abdullah O. Alenezi, Satheesh Krishna, Mishal Mendiratta-Lala, Ania Z. KielarAbstractImaging of primary hepatic neoplasms in patients at risk for hepatocellular carcinoma (HCC) and in patients with otherwise normal livers relies on proper multi-phase image acquisition technique, with emphasis on a high-quality, late arterial phase, using either CT or MRI for accurate image interpretation. The introduction of LI-RADS (Liver imaging Reporting and Data System) in 2011, with subsequent multiple updates, the most recent in 20...

Imaging of Renal Cancer
Publication date: Available online 10 December 2019Source: Seminars in Ultrasound, CT and MRIAuthor(s): Satheesh Krishna, Ashley Leckie, Ania Kielar, Robert Hartman, Ashish KhandelwalAbstractCystic renal masses are common incidental findings on cross-sectional imaging. Accurate characterisation of cystic renal masses is essential to guide management. Renal mass protocol comprises of a good quality non-contrast, corticomedullary and nephrographic phases with each phase providing complementary information for diagnosis. Attenuation measurements in different phases are central to the ‘golden-rules’ in renal mass imaging i...

Infections of the male and female reproductive system: Spectrum of imaging findings
This article will review the relevant embryology and anatomy of the male and female reproductive systems and will discuss the imaging findings of different infections. An understanding of the clinical presentation and imaging findings of infections of the reproductive system is critical in order to allow for prompt and accurate diagnosis. A delay in diagnosis for these infections can have significant morbidity, and occasional mortality. (Source: Seminars in Ultrasound, CT and MRI)

Radiologic Imaging of Bowel Infections
Publication date: Available online 14 October 2019Source: Seminars in Ultrasound, CT and MRIAuthor(s): C. Duffin, S. Mirpour, T. Catanzano, C. MooreAbstractAlthough radiologic imaging of bowel infections is often a precursor to definitive diagnosis by endoscopy, biopsy, or stool cultures, imaging can provide critical information for diagnosis and management. Many infectious entities such as viral, bacterial, and parasitic infections can be discovered on imaging. Furthermore, imaging characterizes the extent of infection, involvement of specific bowel segments, and presence of complications in the abdomen. Utilizing a multi...

Role of Interventional Radiology in the Management of Infection
Publication date: Available online 14 October 2019Source: Seminars in Ultrasound, CT and MRIAuthor(s): D. Hynes, P. Aghajafari, B. Janne d'OthéeInterventional Radiology (IR) is plays a crucial role in the management of localized infections, utilizing percutaneous access to loculated fluid collections for drainage and source control. Interventions have been developed in multiple organs and systems and used over decades, allowing the IR physician to provide patient care in many cases where surgical options are not optimal. In this review, we will examine the emergent, urgent and routine nature of various IR procedures in th...

Role of Nuclear Medicine in Imaging
Publication date: Available online 14 October 2019Source: Seminars in Ultrasound, CT and MRIAuthor(s): A Sureshkumar, B Hansen, D ErsahinAbstractNuclear medicine (NM) plays a unique role in the detection of infection and inflammation. This review looks at different methods that are used for detection of infections and explains how they differ from cross sectional imaging such as CT and MRI. Images are provided to aid understanding and interpretation of NM scans. There is also a brief discussion of future techniques that can alter the use of NM for infection work up.
