PURPOSE: To evaluate whether enhancement of breast cancer on pre-treatment dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) as evaluated semi-quantitatively using computer-aided detection (CAD) is associated with response to neo-adjuvant chemotherapy. MATERIALS AND METHODS: A total of 84 women, (mean age, 51±10 [SD] years; range: 30-73 years) with 84 breast cancers who underwent MRI before neo-adjuvant chemotherapy were included in this retrospective study...

PURPOSE: The purpose of this study was to review and compare outcomes between percutaneous sclerotherapy and transjugular intrahepatic portosystemic shunt (TIPS) treatments in patients with peristomal variceal bleeding. MATERIALS AND METHODS: Ten patients who underwent sclerotherapy (n = 3 patients), TIPS placement (n = 5 patients) or both (n= 2 patients) for peristomal variceal bleeding were retrospectively reviewed. There were 6 women and 4 men, with a mean age of 62...

PURPOSE: To analyze the influence of radiologic expertise in detecting lung tumors on chest radiographs. MATERIALS AND METHODS: We retrieved posteroanterior chest radiographs and CT examination obtained from 283 patients with solitary primary malignant lung tumors who underwent surgical resection. There were 176 men and 107 women with a mean age of 67.0±9.1 (SD) years (range: 33-88 years). Thirteen first-year post-graduate (PGY-1) trainees and nine pulmonary specialists (three radiologists, three thoracic surgeons, and three pulmonologists) interpreted the chest radiographs...

PURPOSE: The purpose of this study was to compare patency rates and risk of obstruction of catheter exchange (CE) with that of CE with fibrin sheath angioplasty (CE+FSA) in dysfunctional tunneled central hemodialysis venous catheter (CHVC). MATERIALS AND METHODS: A total of 107 consecutive patients with dysfunctional CHVC were retrospectively included. There were 66 men and 41 women with a mean age of 67.8±12.5 (SD) years (range: 23.0-86.0 years). Seventy-three of 107 patients (68...

OBJECTIVE: The purpose of this study was to retrospectively evaluate the safety and efficacy of posterior transperineal drainage in patients with presacral abscess. MATERIALS AND METHOD: The records of 21 patients (14 men, 7 women; mean age: 62.1±10 years) who underwent posterior transperineal drainage for the treatment of presacral abscess, either using fluoroscopy or computed tomography guidance, were retrospectively reviewed. Data were analysed with respect to technical success, tolerance, duration of drainage, complications and short-term outcome...

PURPOSE: The purpose of this study was to quantify the distribution of trabeculated (T) and compact (C) left ventricular (LV) myocardium masses in a healthy Caucasian population against age, gender and LV parameters, and to provide normal values for T, C and T/C. MATERIALS AND METHODS: One hundred and forty healthy subjects were prospectively recruited and underwent cardiac MRI at 1.5T with a stack of short-axis cine sequences covering the entire LV. End-diastolic volume (EDV), C and T masses were quantified using a semi-automatic method...

Background parenchymal enhancement (BPE) on breast magnetic resonance imaging (MRI) is a dynamic process, which varies among women and within the same woman over time due to different factors. BPE has profound implications for women with or at risk of breast cancer. Breast radiologist should be aware of factors that could potentially influence BPE and have to be familiar with its typical appearance. Marked BPE could indeed affect the diagnostic accuracy of breast MRI, but this shortcoming can be minimized through evaluation by dedicated radiologists, in order to correctly interpret and properly manage the additional findings...

PURPOSE: The purpose of this study was to assess the precision of four-dimensional (4D) phase-contrast magnetic resonance imaging (PCMRI) to measure mean flow and peak velocity (Vmax ) in a pulsatile flow phantom and to test its sensitivity to spatial resolution and Venc. MATERIAL AND METHODS: The pulsatile flow phantom consisted of a straight tube connected to the systemic circulation of an experimental mock circulatory system. Four-dimensional-PCMR images were acquired using different spatial resolutions (minimum pixel size: 1...

PURPOSE: The purpose of this study was to compare the trans-abdominal (TA) and trans-oral (TO) approaches for fluoroscopic-guided gastrostomy tube placement in patients with chronic ascites. MATERIALS AND METHODS: A 10-year review of clinical imaging and medical records at a single institution identified 29 patients with chronic recurrent ascites who underwent gastrostomy (GT) or gastro-jejunostomy tube (GJT) placement. In 22 patients (18 women, 4 men) aged from 22 to 76 years of age (mean age, 57...

PURPOSE: To report the postoperative magnetic resonance imaging (MRI) features after superior semicircular canal plugging in patients with Minor syndrome. MATERIALS AND METHODS: The MRI examinations with 3D T2-weighted SPACE sequence of 12 patients with superior semicircular canal dehiscence syndrome (SCDS) were retrospectively assessed. Two radiologists independently evaluated the presence of a filling defect of the superior semicircular canal above the superior ampulla and the common crus using an oblique plane parallel to the superior semicircular canal (Pöschl's plane)...

PURPOSE: To identify variables associated with inconclusive ultrasound examination and the need for further abdominopelvic computed tomography (CT) examination for the diagnosis of acute appendicitis. MATERIALS AND METHODS: A total of 105 adult patients with acute appendicitis were included. There were 55 patients (38 men, 17 women; mean age, 23±9 [SD] years; range: 15-58 years) with a diagnosis of acute appendicitis using ultrasound alone and 50 patients (30 men, 20 women; mean age, 31±14 [SD] years; range: 16-83 years) who required further CT...

Prostate interventional magnetic resonance imaging (MRI) is now routinely performed in many centers. Its more widespread acceptance is limited by the cost of the use of MRI largely related to the long duration time of the procedures. However, the benefit of a robotic assistance has generated a new interest, because it substantially shortens the procedure time, while improving the accuracy. MRI-guided biopsy is considered as an appealing alternative to transrectal ultrasound (TRUS)-guided fusion biopsy, given the limitations of TRUS-MRI image registration systems...

Adnexal lesions are routinely encountered in general practice. Ultrasound is the first line of investigation in determining the benign or malignant potential of an adnexal lesion. In the cases of classic simple cysts, hemorrhagic cysts, endometriomas, dermoids and obviously malignant lesions, ultrasound may be sufficient for management recommendations. In cases where there is an isolated adnexal lesion, without peritoneal disease or serum CA-125 elevation, and in lesions considered indeterminate on ultrasound, MR imaging with incorporation of the ADNEx MR score can increase the specificity for the diagnosis of benignity or malignancy...

PURPOSE: To evaluate the feasibility and reproducibility of artificial intelligence software (Smartplanes® ) to automatically identify the transthalamic plane from 3D ultrasound volumes and to measure the biparietal diameter (BPD) and head circumference (HC) in fetus. MATERIAL AND METHODS: Thirty fetuses were evaluated at 17-30 weeks' gestation. For each fetus two three-dimensional (3D) volumes of the fetal head along with one conventional two-dimensional (2D) image of the transthalamic plane were prospectively acquired...
