An Enlarging Metastatic Calcified Liver Lesion of an Occult Melanoma
Calcified liver lesions are caused by a wide variety of factors. The most common lesions are inflammatory liver lesions followed by benign and malignant neoplasms. Hemangioma, one of the most common benign hepatic neoplasm in adults, often contains calcifications, in up to 20% of cases secondary to fibrosis and thrombosis of blood vessels. These calcifications are typically large, coarse, and located in the center of the lesions. Liver metastases, the most common malignant lesions found in the noncirrhotic liver, may contain areas of calcification. Radiologists should be aware of morphologic imaging features of calcified l...

Induction Chemoradiotherapy Versus Chemotherapy Alone for Superior Sulcus Lung Cancer
Superior sulcus tumors are the most challenging group of non-small-cell lung cancers (NSCLC) to treat successfully. Originally these uniformly fatal tumors were described in 1932 by radiologist Henry Pancoast whose name is commonly attached to this malignancy [1]. In the 1950 ’s, the strategy of induction radiotherapy followed by aggressive surgery with en bloc resection of the involved chest wall resulted in up to a 30% long-term cure [2,3].

A rare cause of obstructive jaundice: Cecal herniation through the foramen of winslow
Ivan Welaratne, Afshin NasoodiJournal of Clinical Imaging Science 2018 8(1):24-24 Internal abdominal hernias are rarely reported in the literature and have a very low rate of preoperative diagnosis. It is even rarer that they present with jaundice. A 59-year-old Caucasian female presented with a short history of jaundice, dark urine, epigastric pain, vomiting, and obstipation. Her liver biochemistry profile revealed a mixed cholestatic/hepatocellular pattern with significantly elevated bilirubin. She urgently underwent abdominal imaging which provided a preoperative diagnosis of internal herniation of the cecum within the...

Assessment of the inferior petrosal sinus on T1-Weighted contrast-enhanced magnetic resonance imaging
Conclusions: Our analysis indicates that routine thin-slice contrast-enhanced T1-weighted MRI can provide sufficient anatomic detail to identify typical drainage pattern of the IPS in a majority of cases. In cases where routine drainage was not identified, spatial resolution was not sufficient to further delineate complex drainage anatomy. No correlation was observed between the TS/SS dominance and patency of the ipsilateral IPS. (Source: Journal of Clinical Imaging Science)

AbstractTo compare reverse left ventricular (LV) remodeling after transcatheter aortic valve replacement (TAVR) between patients with bicuspid aortic valve (BAV) and tricuspid aortic valve (TAV).

AbstractThe aim was to compare computed tomography (CT) features in acute and chronic aortic dissections (AADs and CADs) and determine if a certain combination of imaging features was reliably predictive of the acute versus chronic nature of disease in individual patients. Consecutive patients with aortic dissection and a chest CT scan were identified, and 120 CT scans corresponding to 105 patients were reviewed for a variety of imaging features. Statistical tests assessed for differences in the frequency of these features. A predictive model was created and tested on an additional 120 CT scans from 115 patients. Statistic...

Imaging findings of concealed intra-amniotic hemorrhage in the setting of placenta previa and placenta accreta spectrum disorder
AbstractPlacental abruption is an important cause of feto-maternal hemorrhage, with significant impact on both fetal and maternal mortality. In most cases, it presents with abdominal pain and vaginal bleeding. However, vaginal bleeding may be absent with concealed intra-amniotic hemorrhage, as in cases with placenta previa, hence confounding this diagnosis. In such cases, imaging studies may be obtained to evaluate for abdominal pain in pregnancy; hence, radiologists should be aware of the ultrasound and magnetic resonance (MR) imaging appearance of intra-amniotic hemorrhage. This includes presence of markedly echogenic am...

Rationale and design of advantage (additional diagnostic value of CT perfusion over coronary CT angiography in stented patients with suspected in-stent restenosis or coronary artery disease progression) prospective study
Recent studies demonstrated a significant improvement in the diagnostic performance of coronary CT angiography (CCTA) for the evaluation of in-stent restenosis (ISR). However, coronary stent assessment is still challenging, especially because of beam-hardening artifacts due to metallic stent struts and high atherosclerotic burden of non-stented segments. Adenosine-stress myocardial perfusion assessed by CT (CTP) recently demonstrated to be a feasible and accurate tool for evaluating the functional significance of coronary stenoses in patients with suspected coronary artery disease (CAD).

AbstractLesion to subcutaneous nerves is a well-known risk of orthopedic surgery and a significant cause of postoperative pain and dissatisfaction in patients. High-resolution ultrasound can be used to visualize the vast majority of small subcutaneous nerves of the upper and lower limbs. Ultrasound detects nerve abnormalities such as focal hypoechoic thickening, stump neuroma, and scar encasement, and provides information not only about the peripheral nerve itself but also about its relationship to adjacent anatomical structures. The purpose of this review is to provide an overview of the anatomy of the main subcutaneous n...

There are considerable pressures for a rapid return, but players who return to competition too soon have an increased risk of recurrent muscle injuries, which are associated with longer lay-offs. Imaging plays a key role in achieving the correct diagnosis, and magnetic resonance imaging (MRI) has emerged as the method of choice for skeletal muscle imaging.
