Purpose of Review The article represents the value of imaging including conventional multidetector computed tomography (MDCT) and dual-energy computed tomography (DECT) in the evaluation and diagnosis of various pathologies associated with acute abdominal pain in the elderly population. Recent Findings Advances in DECT have dramatically improved t...

Advancing medical technology revolutionizes our ability to diagnose various disease processes. Conventional Single-Energy Computed Tomography (SECT) has multiple inherent limitations for providing definite diagnoses in certain clinical contexts. Dual-Energy Computed Tomog-raphy (DECT) has been in use since 2006 and has constantly evolved providing...

The liver, spleen, and kidneys are the commonest injured solid organs in blunt and penetrating trauma. The American Association for the Surgery of Trauma (AAST) Organ Injury Scale (OIS) is the most widely accepted system for categorizing traumatic injuries. Grading systems allow clear communication of findings between clinical teams and assign a me...

Traumatic bowel and mesenteric injuries (TBMI) have significant morbidity and mortality. The physical examination is often limited and sometimes not feasible in the trauma patient. Multidetector CT (MDCT) detection of TBMI is challenging and can be life-saving. Dual-energy CT (DECT) utilizes iodine overlay, monoenergetic imaging, and metal artifact...

A mass casualty incident (MCI) is an event that generates more patients at one time than locally available resources can manage using routine procedures. By their nature, many of these incidents have no prior notice but result in large numbers of casualties with injuries that range in severity. They can happen anywhere and at any time and regional...

Purpose: To evaluate the role of virtual monoenergetic imaging (VMI) in the detection of peritoneal metastatic disease in contrast-enhanced computed tomography (CT) of the abdomen and pelvis and to compare this technique to the conventional 120 kV mixed dataset. Materials and methods: Institutional review board approval was obtained with no info...

Purpose This retrospective study reports the frequency and severity of coronary artery motion on dual-source high-pitch (DSHP), conventional pitch single-source (SS), and dual-source dual-energy (DE) CT pulmonary angiography (CTPA) studies. Methods Two hundred eighty-eight consecutive patients underwent CTPA scans for suspected pulmonary embolism...

PURPOSE To evaluate the role of virtual monochromatic imaging (VMI) in the detection of peritoneal metastatic disease in contrast-enhanced computed tomography (CT) of the abdomen and pelvis and to compare this technique to conventional polychromatic imaging (PCI). METHOD AND MATERIALS Institutional review board approval was obtained, with no inform...

Purpose: The objective of this study is to establish the effect of third-generation integrated circuit (IC) CT detector on objective image quality in full- and half-dose non-contrast CT of the urinary tract. Methods: 51 consecutive patients with acute renal colic underwent non-contrast CT of the urinary tract using a 128-slice dual-source CT bef...

PURPOSE/AIM 1. Review the variety of pathophysiology causing patients to present with acute left lower quadrant (LLQ) pain 2. Discuss the imaging modalities and imaging characteristics used in diagnosis of LLQ pain CONTENT ORGANIZATION -Review the anatomy and the different causes resulting in patients presenting with acute LLQ pain -Review the im...

PURPOSE/AIM 1. Review the underlying cases which require renal imaging & modalities used 2. Describe important radiologic manifestations, the AAST grading its limitations and the benefit of a CT grading scheme. 3. Show imaging examples of different grades of renal injury, frequent complications and clinical implications of the grading scale for the...

PURPOSE/AIM 1. Review imaging modalities for pancreatic trauma with emphasis on MDCT as modality of choice. 2. Introduce new classification and characteristic findings of pancreatic injuries on MDCT and its implications on management and prognosis. 3. Review a proposed imaging and management algorithm for pancreatic trauma, including indications fo...
