Breast density notification laws, passed in 19 states as of October 2014, mandate that patients be informed of their breast density. The purpose of this study is to assess the impact of this legislation on radiology practices, including performance of breast cancer risk assessment and supplemental screening studies. A 20-question anonymous web-base...
Article
Purpose: To describe the impact of California Breast Density Notification law (SB 1538) on policy development, policy implementation and supplemental screening strategies within California medical facilities. SB 1538 mandates that breast density information be given to patients but provides no funding for supplemental screening, no guidance on how...
Article
Radiology reports are the major, and often only, means of communication between radiologists and their referring clinicians. The purposes of this study are to identify referring physicians' preferences about radiology reports and to quantify their perceived value of multimedia reports (with embedded images) compared with narrative text reports. We...
Article
Spillage of gallstones into the abdominal cavity, referred to as "dropped gallstones" (DGs), occurs commonly during laparoscopic cholecystectomy. The majority of these spilled stones remain clinically silent; however, if uncomplicated DGs are not correctly identified on subsequent imaging, they may mimic peritoneal implants and cause unduly concern...
Article
To describe the short-term efficacy of a strategy of imaging-guided endovascular intervention for the treatment of patients with established postthrombotic syndrome (PTS). The medical records of 183 patients with venous disease who were seen in a single interventional radiology clinic were retrospectively reviewed. Study inclusion criteria were (i)...
Article
The postthrombotic syndrome (PTS) is a frequent cause of chronic pain, swelling, ulceration, and disability in patients with lower extremity deep vein thrombosis (DVT). As interventional radiologists are consulted on more patients with chronic DVT and PTS, their management strategies must be informed by a balanced understanding of the different fac...
Conference Paper
PURPOSE Post-Thrombotic Syndrome (PTS) is a frequent cause of chronic pain, swelling, and disability in patients with deep vein thrombosis, and currently has no consistently effective treatment. The purpose of this study is to describe the feasibility of and initial clinical response to a strategy of imaging-guided endovascular intervention for the...
Conference Paper
PURPOSE/AIM The purpose of this exhibit is: 1) To review the underlying pathologic changes that create the imaging appearances of congenital bronchial atresia on CT 2) To systematically describe the imaging features of congenital bronchial atresia diagnosed on MDCT in adults CONTENT ORGANIZATION Pathologic Changes in Congenital Bronchial Atresia D...

... 6 However, results are mixed as to whether density legislation leads to appropriate clinical translation, in terms of breast cancer risk assessment and supplemental screening, 9 or serves as a source of confusion for both women and clinicians. [10][11][12][13] e addition of breast density in breast cancer risk prediction tools more accurately discriminates cancer risk 14,15 and provides an opportunity to share with women a highly relevant and underappreciated risk factor. Hence, effective interventions that support women in breast health with risk assessment, clinical education, targeted screening recommendations, and shared decision-making should be evaluated for alignment within clinical care. ...
... One study found that among 110 breast imaging facilities (in 34 states and 1 in Canada), 98% of facilities used visual interpretation (BI-RADS categories), while just 2% used a computer-based quantitative determination with or without visual assessment (Nayak et al., 2016). One California survey of 9 breast imaging facilities found that 8 out of 9 facilities estimated breast density by visual methods, and 1 of the 9 used a computer program (Ikeda et al., 2013). ...
... 30,31 Systemic thrombolysis results in a greater reduction in Yi-Jia Su et al. the occurrence of PTS than anticoagulant treatment alone, but it increases the risk of major bleeding, including ICH. 32,33 Catheter-based endovascular therapy with CDT or PCDT has revolutionized the treatment of DVT by reducing the dose and systemic exposure of thrombolytic agents, and it is associated with a very low risk of ICH. 34 The catheter is left in the occluded vein and infusion of a thrombolytic agent usually continues for at least 24 hours. Many studies have demonstrated the efficacy of CDT in restoring venous patency and reducing PTS in the treatment of DVT. ...
... Thus, radiology's early IMR development aims to meet other providers' needs, for example, a group of medical, surgical, and radiation oncologists interested in findings of a diagnostic radiology CT. IMR for oncologic purposes may be a competitive differentiator for practices, as they may integrate a number of features that make consuming images and text together more user friendly for groups of downstream physicians [39][40][41][42][43][44]. ...
... Deep-seated abscesses and larger stones may also require an exploratory approach [19 ,20] . Abscesses due to dropped gallstones are notorious for re-accumulation despite complete percutaneous drainage, with the gallstone acting as a nidus of infection [21] . Larger stones ( > 1 cm) may be fragmented by ultrasonic lithotripsy and rigid endoscopy. ...
... In the present study 4 patients were diagnosed with parotid tumors and 1 patient with parotid abscess before surgery. The definitive diagnosis of actinomycosis of the parotid gland is made by microbiologic or histopathologic findings (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11). However, the culture of Actinomyces is difficult due to the anaerobic nature of the organism (4,5,10). ...
... On prevention of DVT for patients with calf fractures, American College of Chest Physicians guidelines suggest no chemical prophylaxis, whereas the German and French guidelines recommend pharmacologic thromboprophylaxis [11,12]. The majority of literature on DVT emphasizes that thromboprophylaxis for injury-induced lower-limb immobilization is more effective and cost-efficient compared with no thromboprophylaxis [13][14][15]. The controversy between the guidelines and findings in studies partially results from the limited sample size, numerous confounding covariables and heterogeneity of the research subjects, all of which compromise the power of the evidence to some extent. ...
... Percutaneous recanalization combined with endovenous angioplasty and stenting have progressively replaced open surgery as a method to treat PTS. This paradigm shift is supported by several case series findings highlighting its safety and effectiveness [9][10][11][12][13][14][15][16][17][18]. According to the meta-analysis by Qiu et al., including 489 patients from seven studies, the primary, primary assisted, and secondary patency rates at 12 and 36 months were 83.36%, 90.59%, and 94.32%, and 67.98%, 82.26%, and 86.10%, respectively [18]. ...
