OBJECTIVE To evaluate retrospectively the clinical effectiveness of FlightPlan for Liver (FPFL), an automated tumor-feeding artery detection software in cone-beam CT angiography (CBCTA), in identifying tumor-feeding arteries for the treatment of hepatocellular carcinoma (HCC) using three different segmentation sensitivities. MATERIALS AND METHODS The study included 50 patients with 80 HCC nod...

Methods This is a retrospective cohort study carried out at the Orenburg Municipal Perinatal Center and Maternity Hospital No 2 from 2006 to 2012. In this study 3760 pregnancy outcomes were analyzed. The estimated fetal sonographic weight by Hadlock’s formula was obtained within the last week prior to delivery. The study population was divided into 4 groups (true positive, true negative, false ...

AIM To compare the prostate antigen 3 (PCA3) test with (1)H-magnetic resonance spectroscopic imaging ((1)H-MRSI) and dynamic contrast-enhanced magnetic resonance imaging (DCEMR) combined examination in the detection of prostate tumor foci in patients with persistently elevated prostate-specific antigen (PSA) levels and prior negative random transrectal ultrasound (TRUS)-guided biopsy. PATIENT...

STUDY OBJECTIVE To determine the ability of emergency department (ED) physicians to diagnose cholelithiasis with bedside ultrasound. METHODS ED gallbladder ultrasounds recorded over 37 months were compared to radiology ultrasound interpretation. RESULTS Of 1,690 ED gallbladder ultrasound scans performed during this period, radiology ultrasound was performed in 575/1690 (34%) cases. ED physi...

Purpose To evaluate preoperative magnetic resonance imaging (MRI) criteria for their ability to predict the complete removal of parasellar pituitary macroadenoma on the 3-month postoperative MRI. Methods Dedicated pre- and postoperative pituitary MRI studies were reviewed in 49 patients who had undergone transsphenoidal surgery for macroadenomas with potential unilateral parasellar involvement....

A marker's capacity to predict risk of a disease depends on disease prevalence in the target population and its classification accuracy, i.e. its ability to discriminate diseased subjects from non-diseased subjects. The latter is often considered an intrinsic property of the marker; it is independent of disease prevalence and hence more likely to be similar across populations than risk predicti...

Background: To demonstrate the diagnostic accuracy of an integrated approach of blind trans-bronchial needle aspiration (TBNA) and Tc-2-methoxy-isobutyl-isonitrile single photon emission computed tomography (Tc-MIBI-SPECT) in diagnosing mediastinal lymph adenopathy. Methods: Sixty-one consecutive patients with mediastinal lymph adenopathy undergoing both TBNA and Tc-MIBI-SPECT were prospectivel...

Objectives: Presence/absence of cervical lymph node metastasis plays a critical role in prognosis and survival of patients with oral squamous cell carcinoma (SCC). This study was designed to assess the diagnostic accuracy of computed tomography (CT) scan for detection of cervical lymph node metastasis in oral SCC in comparison with histopathological analysis after neck dissection Methods: In...

PURPOSE To compare the diagnostic value of 99Tcm-MIBI- SPECT and 18F-FDG-PET/CT in differentiating benign from malignant solitary pulmonary nodules (SPNs). METHODS 170 SPNs were involved in this study (78 with 99Tcm-MIBI-SPECT and 92 with 18F-FDG-PET/CT). Definite diagnosis of SPNs was determined by biopsy. The diagnostic efficiency of 99Tcm-MIBI-SPECT and 18F-FDGPET/ CT in differentiating be...

INTRODUCTION Cardiac biomarkers may be invaluable in establishing the diagnosis of acute myocardial infarction (AMI) in the ED setting. OBJECTIVE To assess the diagnostic indices of the Cardio Detect assay and the quantitative cardiac troponin T test, in diagnosing AMI in the ED, according to the time of onset of chest pain. METHODOLOGY A total of 80 eligible patients presenting with ischem...
