Objective: To compare the effectiveness of plasma D-dimer levels with findings of 128-slice spiral computed tomography pulmonary angiography (CTPA) in patients with clinical suspicion of pulmonary embolism.
Study Design: Retrospective observational study
Place and Duration of Study: Department of Computed Tomography, Armed Forces Institute of Radiology & Imaging, Pak Emirates Military Hospital Rawalpindi, from Jan 2018 to Dec 2018.
Methodology: A total of 59 patients were inducted who presented in Emergency Department, Pak Emirates Military Hospital Rawalpindi with clinical suspicion of Pulmonary Embolism. The main symptoms were shortness of breath and chest pain. Plasma D-dimer levels of all patients were sent to laboratory and CTPA was performed at Computed Tomography department, Armed Forces Institute of Radiology & Imaging using 128-slice spiral computed tomography.
Results: 36 patients (61%) were males and 23 (39%) were females with an average age of 48.03 ± 18.06 years (range 23-85 years). Out of 59 patients, D-dimer levels were raised in 28 cases (47.4%) while 31 patients (52.6%) showed normal levels. Pulmonary Embolism was detected by CTPA in 30 cases (50.8%) while 29 patients (49.2%) were without obvious abnormality.
Conclusion: Plasma D-Dimer levels show low sensitivity, specificity and negative predictive value and cannot exclude Pulmonary Embolism without CTPA. Computed Tomography Pulmonary Angiography (CTPA) remains diagnostic modality of choice for definitive assessment of Pulmonary Embolism in patients reporting at the emergency reception.
Objective: To review all the patients of spinal dysraphism referred to our center over a three year period in order to identify the most typical neuro-radiological appearances on Magnetic Resonance Imaging.
Study Design: Cross sectional study.
Place and Duration of Study: Armed Forces Institute of Radiology and Imaging, Rawalpindi from Jan 2016 to Dec 2018.
Methodology: MR spine reports of 144 patients of spinal dysraphism were retrospectively analyzed. Age, gender, indication for MRI, operative status, and neuro-radiological features (including site and type of lesion) were recorded for these patients.
Results: Congenital spinal malformations were more frequent among females87 (60.4%) and between 0-20 years 135 (93.9%) of age. Tethered cord 97 (67.4%) was the most common congenital spinal abnormality followed by spina bifida, diastematomyelia, vertebral segmentation anomalies, myelomeningocele, menigocele. Lip-myelomeningocele, lipoma of filum terminale, and sacral agenesis. Frequently observed associated abnormalities included scoliosis 61 (42.4 %), syrinx 47 (32.6%) and dural ectasia 40 (27.8 %).
Conclusion: Congenital spinal malformations are usually complex with variable radiological appearances. Modern high resolution MRI screening is the examination of choice for identification, preoperative evaluation, and long term follow up of such congenital anomalies.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
