Computed tomography (CT) of the abdomen and pelvis was performed in 47 patients who were in complete clinical remission from ovarian carcinoma. Results of CT were correlated with surgical-pathologic findings at surgical reexploration. Overall, CT had a sensitivity of 0.32, specificity of 0.77, positive predictive value of 0.79, and negative predictive value of 0.30. Accuracy of CT did not vary by intraperitoneal or retroperitoneal site studied. Computed tomography detected only 7% of tumor nodules 1 cm or less in diameter and only 37% of nodules over 1 cm in diameter. The utility of CT in this clinical setting was limited to approximately 20% of patients with true-positive CT findings who might have been saved surgical reexploration. Due to a high false-negative rate, a normal CT cannot replace a second-look laparotomy for accurate assessment of disease status.

Assessing Glenoid Defects in Anterior Shoulder Instability: Comparison of a Simple Linear Formula Method With Traditional Methods Using 3-Dimensional Computed Tomography.
Am J Sports Med

Sports Medicine Center, West China Hospital, Sichuan University, Chengdu, China.
Background: Anterior glenoid bone defects significantly influence surgical outcomes in shoulder instability cases. Various measurement methods based on 3-dimensional computed tomography (3D-CT) have been developed. Recently, the simple linear formula method, which establishes a correlation between glenoid height and width, has emerged as a promising technique.

Purpose: Identifying muscles linked to postoperative physical function can guide protocols to enhance early recovery following total hip arthroplasty (THA). This study aimed to evaluate the association of preoperative pelvic and thigh muscle volume and quality with early physical function after THA in patients with unilateral hip osteoarthritis (HOA).
Methods: Preoperative Computed tomography (CT) images of 61 patients (eight males and 53 females) with HOA were analyzed.
High risk of drug-resistant tuberculosis in IGRA-negative contacts: should preventive treatment be considered?

Department of Clinical Infectious Diseases, Research Center Borstel, Leibniz Lung Center, Parkallee 35, Borstel, Germany.
Purpose: Deciding whether to provide preventive treatment to contacts of individuals with multidrug-resistant (MDR) tuberculosis is complex.
Methods: We present the diagnostic pathways, clinical course and outcome of tuberculosis treatment in eight siblings from a single family. Tuberculosis disease was diagnosed by Mycobacterium tuberculosis culture and molecular detection of M.
Diagnostic Certainty in Characterizing Liver Lesions in Rectal Cancer: Abbreviated Liver MRI versus CT.

Department of Surgery and Cancer, Imperial College London, London, UK.
Background: Early diagnosis of metastases is crucial but routine staging with contrast-enhanced multidetector computed tomography (ceMDCT) is suboptimal. A total of 20% will have indeterminate or too small to characterize (TSTC) liver lesions on CT, requiring formal characterization by magnetic resonance imaging (MRI). This UK cross-sectional study reports our experience undertaking routine abbreviated liver MRI (MRI).

Department of Restorative Dentistry, School of Dentistry of Ribeirão Preto, University of São Paulo (USP), Ribeirão Preto, SP, Brazil.
Objectives: To evaluate cases of persistent apical periodontitis (PAP) and what are the imaging and clinical aspects that could be considered in the PAP diagnosis and in their treatment decision-making process.
Methodology: 423 patients with apical periodontitis at the time of non-surgical root canal treatment (NSRCT) were followed-up for at least 1 year. Periapical radiographic images were used to compare and determine periapical status at each time using the PAI scoring system.
