Background Revisions of hip prostheses are increasing, and conventional radiography (CR) is a primary tool for managing -complications. However, dual-energy CT (DECT) with virtual monoenergetic imaging is capable of reducing periprosthetic metal artifacts compared with standard CT. Purpose To compare the diagnostic performance of DECT and CR in detecting hip prosthesis loosening, using surgery as a reference for diagnosis.

Being aware of one's own ability to interact socially is crucial to everyday life. After a brain injury, patients may lose their capacity to understand others' intentions and beliefs, that is, the Theory of Mind (ToM). To date, the debate on the association between ToM and other cognitive deficits (in particular executive functions and behavioural disorders) remains open and data regarding awareness of ToM deficits are meagre.

Methods: This prospective IRB-approved study was conducted between January 2019 and October 2019 and included 59 consecutive patients (18 males, 41 females; mean age 61.5 years, range 32-82) who were assessed by DECT and magnetic resonance imaging (MRI) within a 5-day period.
Objective: To describe the chest radiography (CR) and the high resolution CT (HRCT) imaging findings of chronic pulmonary schistosomiasis (CPS).
Methods And Materials: This retrospective study included 10 patients suffering from CPS, studied between September 2013 and October 2016 by using CR and HRCT. Images were reviewed by two experienced radiologists in consensus, blinded to clinical data.

Methods: This prospective institutional review board-approved study included 47 consecutive patients (28 males, 19 females; mean age of 34.2 years) studied between January 2017 and October 2018.
Objective: To evaluate the diagnostic accuracy of dual-energy computed tomography (DECT) to identify bone marrow edema (BME) of the ankle.
Methods: This prospective institutional review board approved study included 40 consecutive patients (29 males and 11 females; mean age of 32.3 years) studied with DECT (80 kV and tin filter 150 kV) and MRI within 10 days.
Article Synopsis
- Evaluation of pancreatic ductal adenocarcinoma (PDAC) post-chemoradiotherapy is complicated by CT overestimating tumor size and vascular involvement, impacting surgical options for patients with resectable tumors.
- A study of 71 patients analyzed the effectiveness of pre-operative imaging (CT/MR) in predicting complete tumor resection, involving assessments by three radiologists for accuracy against anatomical pathology.
- Findings indicated a 25 mm size cut-off was moderately effective for assessing tumor dimensions and R0 resection, with diagnostic accuracy improved in consensus readings, but inter-observer agreement struggled except for larger tumors.
Purpose: The aim of this study was to evaluate DECT diagnostic accuracy in the identification of vertebral bone marrow edema, using MRI as standard of reference.
Methods: This prospective institutional review board-approved study included 76 consecutive patients (29 males and 47 females; mean age 62.3, range 51-82 years) studied with DECT (90 kV and tin filter 150 kV) and MRI within 7 days.
Purpose: The aim of this study was to compare the diagnostic accuracy of magnetic resonance imaging (MRI) and dual-energy computed tomography (DECT) to identify residual-recurrent cholesteatoma using the second-look surgery as the reference standard.
Methods: This prospective, institutional review board-approved study included 19 consecutive patients (11 males and 8 females; mean age of 62.2, range 34-80 years).
Purpose: To evaluate the diagnostic accuracy of wash-out parameters calculated using multiple intermediate and delayed phases.

Small (pT1a-b), node-negative (pN0) breast cancer generally has a good prognosis. However, HER2-positive status is associated with an increased risk of relapse and decreased survival even in these tumors. Although there are only few data from prospective randomized trials, results of retrospective studies suggest adjuvant chemotherapy plus trastuzumab may improve outcomes of patients with pT1a-b pN0 HER2-positive breast cancer.

Unlabelled: : Neuroendocrine carcinoma of the breast is considered a rare entity, and for this reason there are no data from prospective clinical trials on its optimal management. Early stage tumors are usually treated with the same strategy used for the other types of invasive breast cancer. Anthracycline- and taxane-based regimens represent the most frequently administered chemotherapy in neoadjuvant and adjuvant setting, as well as for metastatic disease, although combinations of platinum compounds and etoposide have been widely used, in particular for small-cell histology and tumors with a high proliferation index.
