PURPOSE: We aimed to evaluate the clinical superiority of using C-arm computed tomography (CT) to establish percutaneous nephrolithotripsy (PCNL) access for patients with non-dilated renal collecting systems. METHODS: From May 2014 to May 2015, 33 patients underwent C-arm CT-guided puncture to establish PCNL access after failed attempts of ultrasonography-guided nephrostomy. Technical success, procedure details, radiation exposure, complications, and stone-free rate were recorded...

Retained foreign bodies within the stomach and proximal small bowel may be problematic in patients with prior cerebrovascular injury or head, neck and esophageal malignancy, given the increased vulnerability of this patient population to complications from aspiration and increased difficulty of esophagogastroduodenoscopy in cases of tumoral obstruction. This article presents an alternative method for foreign body retrieval through an existing gastrostomy tract, which offers the benefits of fast procedure times, reduction in radiation dose and fluoroscopy time, and allows for safer retrieval of foreign bodies by using direct visualization...

PURPOSE: A recently identified and treatable cause of spontaneous intracranial hypotension (SIH) is cerebrospinal fluid (CSF)-venous fistula, and a recently described computed tomography myelogram (CTM) finding highly compatible with but not diagnostic of this entity is the hyperdense paraspinal vein sign. We aimed to retrospectively measure the prevalence of the hyperdense paraspinal vein sign on CTMs in SIH patients without dural CSF leak, in comparison with control groups. METHODS: Three CTM groups were identified: 1) SIH study group, which included dural CSF leak-negative standard CTMs performed for SIH, with early and delayed imaging; 2) Early control CTMs, which were performed for indications other than SIH, with imaging shortly after intrathecal contrast administration; 3) Delayed control CTMs, which included delayed imaging...

A 14-year-old boy presented with several months of increasing abdominal girth and fatigue. Imaging confirmed massive ascites and hepatic congestion secondary to central hepatic venous obstruction. Several large intrahepatic collateral veins were seen draining via caudate and emissary veins. After an unsuccessful attempt at retrograde recanalization utilizing intravascular ultrasound, the right hepatic vein was recanalized in an antegrade fashion by way of a prominent caudate collateral vein, and subsequently stented...

PURPOSE: Prostate multiparametric magnetic resonance imaging (mpMRI) has utility in detecting post-radiotherapy local recurrence. We conducted a multireader study to evaluate the diagnostic performance of mpMRI for local recurrence after low dose rate (LDR) brachytherapy. METHODS: A total of 19 patients with biochemical recurrence after LDR brachytherapy underwent 3T endorectal coil mpMRI with T2-weighted imaging, dynamic contrast-enhanced imaging (DCE) and diffusion-weighted imaging (DWI) with pathologic confirmation...

PURPOSE: We aimed to retrospectively compare the local tumor control rates between low frequency (LF) and high frequency (HF) microwave ablation devices in the treatment of <3 cm lung metastases. METHODS: A total of 36 patients (55 tumors) were treated with the LF system (915 MHz) and 30 patients (39 tumors) were treated with the HF system (2450 MHz) between January 2011 and March 2016. Computed tomography (CT) scans performed prior to and 24 hours after the ablation were used to measure the size of the ablation zone and to calculate the ablation margin...

PURPOSE: We aimed to test the hypothesis that doxorubicin (DOX) survives thermal ablative heating in an ex vivo model of combined transarterial chemoembolization (TACE) and thermal ablation. METHODS: Fresh porcine psoas major muscle (3 samples, 15×10×3 cm) was submerged in aqueous DOX solution (60 µg/mL, 0.1 M) for 24 hours to passively saturate tissue. DOX-infused tissue was then dried and treated with microwave ablation (MWA) using a 2.45 GHz antenna at 65 W for 2, 5, and 10 minutes...

PURPOSE: We aimed to investigate patients with lower gastrointestinal bleeding who presented to the emergency department requiring initial conventional angiography. We report risk-stratified and mesenteric conventional angiography outcomes. METHODS: We retrospectively reviewed patients with lower gastrointestinal bleeding between 2001 and 2012. We included all consecutive patients with clinical lower gastrointestinal bleeding with a requirement of further angiography and possible embolization...

PURPOSE: We aimed to compare the diagnostic accuracy and interpretation time of an abbreviated protocol relative to the complete protocol of breast magnetic resonance imaging (MRI) with the use of breast imaging reporting and data system (BI-RADS). Between-reader and between-protocol variability for BI-RADS classification and influence of reader expertise on diagnostic accuracies were also evaluated. METHODS: We conducted a retrospective reader study in 90 women who underwent breast MRI: 30 benign examinations (graded as American College of Radiology [ACR] 1 or 2), 30 examinations graded as ACR 3 and 30 examinations requiring a histologic proof (graded as ACR 4 or 5)...

Most pancreatic ductal adenocarcinomas (PDAs) show solid growth pattern, but ductal adenocarcinomas may demonstrate intratumoral cystic appearance or accompany peritumoral non-neoplastic cystic lesions, thus mimicking cystic pancreatic tumors on imaging studies. The histopathologic findings for PDA with cystic feature are divided into neoplastic and non-neoplastic cysts. Neoplastic cystic changes include large-duct type cysts (microcystic appearance), neoplastic mucin cysts (macrocystic appearance), colloid carcinomas (mucinous noncystic adenocarcinomas), and degenerative cystic change usually caused by hemorrhagic necrosis of tumor...

The purpose of this pictorial essay is to present and summarize findings of various images of chronic granulomatous disease (CGD). CGD represents a heterogeneous group of disorders caused by defective generation of respiratory bursts in human phagocytes. This defect results in abnormal phagocytic functions and defective killing of bacteria by phagocytes. CGD may involve many organs and present with recurrent infections and inflammations. Radiologists should consider the possibility of CGD when a patient presents with atypical and recurrent infection...

Dislodged intrabiliary drainage devices, including catheters, endoprostheses, and stents, may further impair drainage and cause various local reactions, vascular and gastrointestinal tract complications. Endoscopic approaches for management of plastic biliary endoprostheses have been extensively discussed. However, in rare cases of fracture of percutaneous transhepatic biliary drainage (PTBD) catheters, only a percutaneous transhepatic technique for retrieving should be applied to avoid further damage by its rigid fragment...

PURPOSE: We aimed to demonstrate feasibility of the use of a dual-balloon infusion microcatheter for segmental/subsegmental drug-eluting bead transarterial chemoembolization (DEB-TACE). METHODS: Over a 16-month period, 15 segmental and 21 subsegmental DEB-TACE procedures were attempted using a dual-balloon anti-reflux microcatheter (IsoFlow™ microcatheter, Vascular Designs Inc.) in 21 patients (15 males; median age, 61 years; range, 49-82 years) with hepatocellular carcinoma (Barcelona clinic liver cancer stage A [n=4]; B [n=12]; C [n=5]) with one to three tumors, median size of 3...

PURPOSE: We aimed to report a preliminary single-center experience of elective endovascular aortic repair (EVAR) using ultra-low profile (ULP) endografts of 14 F outer diameter. METHODS: Data of 67 consecutive patients who underwent EVAR using either Ovation (group A, n=30) or Incraft (group B, n=37) endografts were retrospectively analyzed. RESULTS: Aorto-iliac anatomy was significantly different between the two groups, as patients of group A had a greater thrombotic apposition on proximal aortic neck (thrombus thickness: 7...

In the medical era of early detection of diseases and tailored therapies, an accurate characterization and staging of the disease is pivotal for treatment planning. The widespread use of computed tomography (CT)-often with the use of contrast material (CM)-probably represents the most important advance in diagnostic radiology. The result is a marked increase in radiation exposure of the population for medical purposes, with its intrinsic carcinogenic potential, and CM affecting kidney function. The radiologists should aim to minimize patient's risk by reducing radiation exposure and CM amount, while maintaining the highest image quality...
