Phlegmasia cerulea dolens in a patient with partial inferior vena cava interruption treated with mechanical thrombectomy.

Phlegmasia cerulea dolens is a rare condition associated with deep vein thrombosis (DVT). Inferior vena cava clips are even more rarely seen devices historically placed in the context of DVT. In this case, a 70-year-old woman with a distant history of DVT presented with acute onset left calf pain, swelling, and discoloration.

ER-Targeted PET for Initial Staging and Suspected Recurrence in ER-Positive Breast Cancer.

Importance: There are insufficient data comparing 16α-18F-fluoro-17β-estradiol (FES) positron emission tomography (PET) computed tomography (CT) with standard-of-care imaging (SOC) for staging locally advanced breast cancer (LABC) or evaluating suspected recurrence.

Objective: To determine the detection rate of FES PET/CT and SOC for distant metastases in patients with estrogen receptor (ER)-positive LABC and recurrences in patients with ER-positive BC and suspected recurrence.

Design, Setting, And Participants: This diagnostic study was conducted as a single-center phase 2 trial, from January 2021 to September 2023.

F-DCFPyL PET/CT for Initially Diagnosed and Biochemically Recurrent Prostate Cancer: Prospective Trial with Pathologic Confirmation.

Background Prostate-specific membrane antigen (PSMA) PET is standard for newly diagnosed high-risk and biochemically recurrent (BCR) prostate cancer. Although studies suggest high specificity of 2-(3-{1-carboxy-5-[(6-[(18)F]fluoro-pyridine-3-carbonyl)-amino]-pentyl}-ureido)-pentanedioic acid (DCFPyL) for targeting PSMA, false-positive findings have been identified and most studies lack histologic confirmation of malignancy. Purpose To estimate the positive predictive value (PPV) of DCFPyL PET/CT by providing histopathologic proof for DCFPyL-avid lesions suspected of being distant metastases at initial diagnosis and recurrence in BCR prostate cancer.

Technical and Anatomic Factors Influencing the Success of Inferior Vena Caval Stent Placement for Malignant Obstruction.

Purpose: To evaluate the outcomes of inferior vena cava (IVC) stent placement for malignant obstruction and to identify anatomic and procedural factors influencing technical and clinical success.

Materials And Methods: A total of 57 patients (37 male, 20 female; age range, 22-86 y) underwent 62 IVC stent placement procedures using 97 stents (47 Wallstents, 15 S.M.

Emergent salvage direct intrahepatic portocaval shunt procedure for acute variceal hemorrhage.

Purpose: To review the safety and effectiveness of direct intrahepatic portocaval shunt (DIPS) creation with variceal embolization for acute variceal hemorrhage after a failed transjugular intrahepatic portosystemic shunt (TIPS) creation attempt or in patients with prohibitive anatomy.

Materials And Methods: Transjugular intrahepatic portosystemic shunt and DIPS procedures performed for variceal hemorrhage between January 2008 and July 2014 were reviewed. The default procedure was TIPS creation, with DIPS creation reserved for patients with unfavorable anatomy or who had technically unsuccessful TIPS creation.

The efficacy of hepatic 90Y resin radioembolization for metastatic neuroendocrine tumors: a meta-analysis.

Unlabelled: (90)Y resin radioembolization is an emerging treatment in patients with liver-dominant metastatic neuroendocrine tumors (mNETs), despite the absence of level I data. The aim of this study was to evaluate the efficacy of this modality in a meta-analysis of the published literature.

Methods: A comprehensive review protocol screened all reports in the literature.

Evolution of coronary computed tomography radiation dose reduction at a tertiary referral center.

Purpose: We aimed to assess the temporal change in radiation doses from coronary computed tomography angiography (CCTA) during a 6-year period. High CCTA radiation doses have been reduced by multiple technologies that, if used appropriately, can decrease exposures significantly.

Methods: A total of 1277 examinations performed from 2005 to 2010 were included.

Aortic distensibility and its relationship to coronary and thoracic atherosclerosis plaque and morphology by MDCT: insights from the ROMICAT Trial.

Background: Multi-detector cardiac computed tomography (CT) allows for simultaneous assessment of aortic distensibility (AD), coronary atherosclerosis, and thoracic aortic atherosclerosis.

Objectives: We sought to determine the relationship of AD to the presence and morphological features in coronary and thoracic atherosclerosis.

Methods: In 293 patients (53 ± 12 years, 63% male), retrospectively-gated MDCT were performed.

Infarct detection with a comprehensive cardiac CT protocol.

Background: Cardiac CT has the potential to offer comprehensive infarct detection by assessing regional wall motion abnormalities (RWMAs), rest perfusion defects (RPDs), and delayed contrast enhancement (DCE). However, the diagnostic accuracy of these techniques for the detection of myocardial infarction (MI) is unknown.

Methods: Forty-eight patients with intermediate-to-high probability for coronary artery disease after single-photon emitting CT myocardial perfusion imaging were prospectively enrolled for a research comprehensive 64-detector row dual-source cardiac CT protocol that included cine images for RWMA, first-pass images for RPD, and delayed images for DCE.

A comparison of reconstruction and viewing parameters on image quality and accuracy of stress myocardial CT perfusion.

Background: Myocardial stress computed tomography perfusion (CTP) has similar diagnostic accuracy for detecting perfusion defects (PDs) versus single-photon emission computed tomography (SPECT). However, the optimal diagnostic viewing and image processing parameters for CTP are unknown.

Objective: We sought to compare the diagnostic accuracy of different image processing techniques, cardiac phases, slice thicknesses, and viewing parameters for detection of PDs.

Stress myocardial CT perfusion: an update and future perspective.

Coronary computed tomography angiography (CTA) has been shown by several multicenter trials to have excellent diagnostic accuracy in the detection and exclusion of significant coronary stenosis. However, a major limitation of coronary CTA is that the physiological significance of stenotic lesions identified is often unknown. Stress myocardial computed tomography perfusion (CTP) is a novel examination that provides both anatomic and physiological information (i.

The effect of heart rhythm on patient radiation dose with dual-source cardiac computed tomography.

Background: To lower the radiation exposure associated with cardiac CT, it is essential to identify all factors that influence radiation dose.

Objectives: We explored the effect of heart rhythm during scan acquisition on radiation dose with a 64-slice dual-source cardiac CT.

Methods: Patient and scan data were collected prospectively in 302 consecutive patients referred for a clinical dual-source cardiac CT.

Cardiovascular disease and stroke in women: role of radiology.

Objective: The purposes of this review are to describe the clinical presentation and diagnostic test characteristics in the care of women with cardiovascular and cerebrovascular disease and to discuss the role of newer imaging modalities in improving diagnostic accuracy in the detection of these diseases.

Conclusion: Despite major advances in both diagnostics and therapeutics, cardiovascular and cerebrovascular diseases remain two of the leading causes of morbidity and mortality among women worldwide. More research is needed into sex differences in these diseases, particularly to discern whether accurate imaging can lead to early diagnosis, change in clinical management, and overall improvement in patient outcomes.

Using Keynote to present radiology images.

Numerous articles have offered instructions for working with advanced radiology images in Microsoft PowerPoint (Redmond, WA); however, no articles have detailed instructions to do the same on alternative presentation software. Apple Macintosh (Cupertino, CA) computers are gaining popularity with many radiologists, due in part to the availability of a powerful, free, open-source Digital Imaging and Communications in Medicine (DICOM) viewing and manipulating software OsiriX ( http://www.osirix-viewer.
