BACKGROUND AND OBJECTIVES The diagnostic yield of push enteroscopy (PE) varies widely from 13 to 78% of cases, according to the various series. The aim of this retrospective cohort study was to determine the endoscopic and histological yield of PE in our health area. PATIENTS AND METHODS A total of 355 consecutive patients (190 males/165 females; mean age 45 years, range 15-89) underwent PE o...

OBJECTIVE To evaluate the diagnostic yield, accuracy, and safety of frame-based stereotactic brain biopsy procedures. METHODS A retrospective study of all pathologically diagnosed intracranial lesions, using frame-based stereotactic guided brain biopsy procedures performed at King Faisal Specialist Hospital and Research Centre (KFSH&RC), Riyadh, Kingdom of Saudi Arabia between 1993 and 2005 w...

BACKGROUND Guidelines for triaging patients for cardiac catheterization recommend a risk assessment and noninvasive testing. We determined patterns of noninvasive testing and the diagnostic yield of catheterization among patients with suspected coronary artery disease in a contemporary national sample. METHODS From January 2004 through April 2008, at 663 hospitals in the American College of C...

BACKGROUND Although endobronchial ultrasound (EBUS)-guided transbronchial biopsy (TBB) has been shown to increase the diagnostic yield over conventional bronchoscopic techniques, an important issue regarding the optimal number of biopsy specimens required has not been thoroughly investigated. OBJECTIVES We sought to examine whether the number of biopsy specimens taken was associated with the ...

Introduction : Diagnosis of peripheral pulmonary nodules is confusing; therefore, an accurate and safe lung biopsy can prevent unnecessary invasive diagnostic procedures. This study soughtto study the diagnostic yield, sensitivity, specificity, and negative and positive predictive values (NPV and PPV) of radial probe endobronchial ultrasound (EBUS)-guided biopsy for peripheral pulmonary lesions...

Diagnostic Yield of Clinical Next-Generation Sequencing Panels for Epilepsy During the past 2 years, next-generation DNA sequencing (NGS) has become a widespread diagnostic tool in neurology. Several studies have addressed the diagnostic yield and cost of NGS relative to other types of DNA testing. G-banded karyotyping identifies chromosomal aberrations and has a 3% diagnostic yield for unexpla...

OBJECTIVES To determine the diagnostic yield of computed tomography scanning of the pulmonary arteries (CTPA) in our centre and factors associated with it. Differences between specialties as well as adherence to protocol were investigated. METHODS All patients receiving a first CTPA for pulmonary embolism (PE) in 2010 were included. Data about relevant clinical information and the requesting ...
