Background: Chorionic villus sampling(CVS) has a major role in prenatal diagnosis . It is an invasive diagnostic method in completion of primary prenatal screenings. This article is a report of our 8 years experience of CVS in Mashhad. Materials and Methods: We have done 1511 cases of invasive diagnostic procedure including 723 CVS which were included in our study and also 788 cases of amniocen...

This study was set up to evaluate retrospectively the efficacy of a standard diagnostic procedure, including non-invasive and invasive (spinal tap, nerve/muscle biopsy) investigations, in the diagnosis of peripheral neuropathy. The medical records of 171 in-patients with the final diagnosis of peripheral neuropathy of determined or undetermined cause were reviewed and each individual diagnostic...

BACKGROUND The evidence base supporting minimally invasive sacroiliac (SI) joint fusion (SIJF) surgery is increasing. The work relative value units (RVUs) associated with minimally invasive SIJF are seemingly low. To date, only one published study describes the relative work intensity associated with minimally invasive SIJF. No study has compared work intensity vs other commonly performed spine...

invasive salmonellosis is common in tropical areas. this study examines the performance of a clinical definition for its recognition among children ages 1 to 14 years admitting to a referral pediatric hospital in tehran. 60 children were enrolled into the study during a period of 51 months. to facilitate analysis, cases were divided into 5 categories according to the likelihood of invasive salm...

Background: Arterial sampling in PET studies for the purposes of kinetic modeling remains an invasive, time-intensive, and expensive procedure. Alternatives to derive blood time-activity curve (BTAC) are either reliant on large vessels field view or laborious implement prone many processing errors. An alternative method is proposed by simulation a non-invasive coincidence detection unit.

This paper presents a magnetic resonance imaging (MRI)-based virtual cystoscopy system, which extracts the bladder wall from T1-weighted MR images where the wall is enhanced while the urine and surrounding fat tissues are suppressed by a fully non-invasive imaging procedure. The system analyzes the extracted wall and detects abnormal features automatically. Test results are encouraging by FROC ...

The Nuss procedure, which is a minimally invasive approach for treating pectus excavatum, has better functional and cosmetic outcomes than other invasive procedures. Cardiac perforation is the most serious complication and several methods for the prevention of intraoperative events has been developed. Although most cardiac injuries are detected in the operating room, in the case described herei...

patients with valvular heart disease suffer from atrial fibrillation for more than 12 months after valve surgery and have a low probability of remaining in sinus rhythm. we performed an intra-operative procedure similar to surgical maze ііі procedure for conversion of this arrhythmia to sinus rhythm. we did this study to evaluate the efficacy of this procedure to restore the sinus rhythm in pat...

African Americans are under-represented in Alzheimer's disease (AD)-related biomarker studies, and it has been speculated that mistrust plays a major factor in the recruitment of African Americans for studies involving invasive procedures such as the lumbar puncture (LP). We set out to determine factors associated with non-participation in a biomarker study aiming to explore cerebrospinal fluid...
