A 64-year-old male patient one year after percutaneous coronary intervention (PCI) with coronary stent implants was admitted with a pulsatile, palpable mass with bruit and intermittent pain in the region of the left radial artery. Finding: Ultrasonography of the left radial artery was performed, confirming a radial arteriovenous fistula (AVF) in the place of PCI. Method: Percutaneous embolization (PE) with thrombin was chosen as a treatment of choice based on the anatomical localization and characteristics of the AVF. The PE treatment was repeated twice with suboptimal post-procedural result. One day after the PE an ultrasonographic check-up was performed, confirming a suboptimal result of PE with a light palpable bruit present in the place of the AVF. Patient was indicated for surgical resection. After the surgical resection, patient was immediately relieved of all accompanying symptoms and was discharged two days after the procedure. Conclusion: The preferred treatment of choice for post-catheterization arteriovenous fistulas is percutaneous embolization. Surgical resection of post-catheterization AVF is used only when all percutaneous treatments fail.","PeriodicalId":13333,"journal":{"name":"Imaging in Medicine","volume":"81 1","pages":"32-34"},"PeriodicalIF":0.0,"publicationDate":"2016-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83405809","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Physicians performing interventional procedures that are guided by X-rays are not immune to these potential dangers despite remaining outside of the primary beam. Contemporary studies regarding deleterious subclinical and clinical effects associated with chronic exposure to medical radiation have raised awareness in the interventional community. In recent years, investigations regarding feasible processes to reduce operator exposure have been published and are summarized in this review. Immediate universal implementation of many of these methods may result in significant decreases in operator and patient exposure. Future research in this field will help further define the risk posed by X-ray guided procedures and lead to a safer interventional environment for patients, operators, and staff.","PeriodicalId":13333,"journal":{"name":"Imaging in Medicine","volume":"105 1","pages":"3-12"},"PeriodicalIF":0.0,"publicationDate":"2016-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85733566","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Growth, structure, and function of these branching structures have an immense effect on our lives. Therefore, quantitative size information on such structures in their native environment is invaluable for studying their growth and the effect of the environment on them. X-ray computed tomography (XCT) has been an effective tool for in situ imaging and analysis of branching structures. We developed a costless tool that approximates the surface and volume of branching structures. Our methodology of noninvasive imaging, segmentation and extraction of quantitative information is demonstrated through the analysis of a plant root in its soil medium from 3D tomography data. XCT data collected on a grass specimen was used to visualize its root structure. A suite of open-source software was employed to segment the root from the soil and determine its isosurface, which was used to calculate its volume and surface. This methodology of processing 3D data is applicable to other branching structures even when the structure of interest is of similar X-ray attenuation to its environment and difficulties arise with sample segmentation.","PeriodicalId":13333,"journal":{"name":"Imaging in Medicine","volume":"15 1","pages":"97-98"},"PeriodicalIF":0.0,"publicationDate":"2016-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77856402","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We describe a case of rectal adenocarcinoma metastatic to the breast. A 21 year old woman had undergone abdominoperineal and vaginal resection and hysterectomy, right inguinal lymph node dissection for presenting vaginal bleeding ten months before. The patient was readmitted to our hospital for presenting edema and masses with severe pain in her breasts. US and contrasted CT was taken but mammography could not be performed due to severe tender and pain of her breasts. Breast US revealed diffuse skin thickening and bilateral multiple well-defined hypoechoic masses whereas contrasted CT delineated multiple, oval or round, and inhomogeneous superficial and invasive deep solid masses in her breasts with strong peripheral and moderate patchy central contrast enhancement and bilateral axillary lymph nodes. Breast biopsy and immunohistochemistry revealed rectal adenocarcinoma metastasis to the breast. To our knowledge, colorectal adenocarcinoma metastasis to the breast in women is extremely rare as 17 patients in the literature. Moreover, this is the fifth patient with bilateral breast metastasis from colorectal adenocarcinoma. This report also shows that CT is helpful to define axillary metastasis, the fixation and invasion of the deep metastatic lesions to the chest wall, which is unique feature of this metastatic tumor. CT could be used for early stage breast metastasis to some extent, but CT was diagnostic in late stage.","PeriodicalId":13333,"journal":{"name":"Imaging in Medicine","volume":"8 1","pages":"89-92"},"PeriodicalIF":0.0,"publicationDate":"2016-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78490814","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Fischman, Rahul S. Patel, D. Siegel, A. Rastinehad","doi":"10.14303/Imaging-Medicine.1000023","DOIUrl":"https://doi.org/10.14303/Imaging-Medicine.1000023","url":null,"abstract":"Tel: 212-241-9955 Benign prostatic hyperplasia (BPH) is a common condition related to aging that can lead to a cluster of chronic symptoms collectively known as lower urinary tract symptoms (LUTS), including urinary frequency, urinary urgency, nocturia, hematuria, and decreased urinary stream. It is estimated that BPH affects 75% of men in the United States by age 70, with more than $1 billion US dollars a year spent in direct health care expenditures related to BPH, exclusive of outpatient medications [1]. Treatment options for BPH are outlined out by the American Urologic Association Clinical Guidelines and include watchful waiting, medical therapy, minimally invasive therapies (including transurethral ablations), or surgical therapies including open prostatectomy or transurethral resection of the prostate (TURP) [2]. Medical therapy is often considered the first-line option for symptomatic patients; however, a large subset of patients does not respond to or cannot tolerate pharmacotherapy, in part owing to a number of side effects including sexual dysfunction [3]. TURP has remained the ‘gold standard’ surgical treatment for BPH for over half a century, owing to its high success rate in reducing LUTS. Over the past two decades, the TURP procedure has undergone significant technical improvements, with morbidity rates reported to be <1% [4]. However, with a general shift towards minimally invasive treatment options, the number of TURPs performed has fallen in more recent years [5]. Manuscript Click here to download Manuscript SAPE final (1).docx Embolization of the prostatic arteries has been used for many years as a technique to control severe bladder and prostate hemorrhage as well as hematuria following TURP [6-9]. A case report by DeMeritt et al in 2000 described a patient with BPH and refractory hematuria treated by prostatic artery embolization, who subsequently had alleviation in his LUTS and reduction in the volume of his prostate [10]. This case report introduced the idea that BPH could intentionally be treated by selective arterial prostatic embolization (SAPE). In 2008, Carnevale et al used SAPE as the primary treatment in two patients with BPH [11]. After 6-month follow-up, MRI demonstrated a relative prostate reduction of 47.8% in the patient who had undergone bilateral SAPE and 27.8% in the patient who had undergone unilateral SAPE. Since this initial study, there has been an enthusiastic response in the literature regarding the future role of this technique, and the Society of Interventional Radiology has encouraged further research into this intervention [12]. A growing body of literature suggests that SAPE enables reduction in prostate volume with improvements in uroflometry parameters, quality of life, and sexual function [13]. The largest prospective non-randomized series published to date looked at 255 patients who underwent SAPE [14]. The authors describe technical success in 250 of the patients (98%), with a clinical success","PeriodicalId":13333,"journal":{"name":"Imaging in Medicine","volume":"37 1","pages":"1-3"},"PeriodicalIF":0.0,"publicationDate":"2016-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73924635","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
