Role of Elastography in Assessment of Enlarged Lymph Nodes

2019 | Keywords Ultrasound Elastography, Enlar, ltrasound Elastography, Enlarged Lymph Nodes, US, CT,
Role of Elastography in Assessment of Enlarged Lymph Nodes
Background: Enlarged lymph node is a marked dilemma in clinical practice. Common causes included; reactive hyperplasia, lymphoma, lymphadenitis, granuloma, metastasis, tuberculosis. Objective: The aim of our study was to evaluate the diagnostic accuracy of shear wave elastography in differentiation between benign and malignant lymphadenopathy and to highlight the adjuvant rule of elastography as a complementary imaging technique to the conventional ...

Diagnostic value of trans rectal ultra-sonography in comparison with MR imaging in detection and characterization of prostatic lesions

2018 | Keywords TRUS, prostate, MRI,
Diagnostic value of trans rectal ultra-sonography in comparison with MR imaging in detection and characterization of prostatic lesions
Abstract Aim:To evaluate the diagnostic accuracy of MRI techniques in detection and characterization of different prostatic lesions in comparison with TRUS. Patient and Methods:This prospective study include TRUS and MRI prostate of 30 adult male patients presented by different prostatic lesions obtained by using 1.5Tmachine, using pelvic phased array coil and/or endorectal coil. Pulse sequences include conventional (T1W&T2W) , MR ... Read more

Value of magnetic resonance imaging measurement of lateral semicircular canal bone island in sensorineural hearing loss patients

2017 | Keywords lateral semicircular canal bon, Magnetic resonance imaging, radiological measurement,
Value of magnetic resonance imaging measurement of lateral semicircular canal bone island in sensorineural hearing loss patients
OBJECTIVE: Dysplasia of lateral semicircular canal (LSCC) is a common inner ear anomaly that may exist in patients with sensorineural hearing loss (SNHL). The diagnosis of subtle anomaly is limited when depending on visual inspection alone to evaluate images. Our purpose is to prove that routine measurement of the bone island of LSCC can avoid missing subtle anomaly and to ... Read more

Benign versus malignant focal liver lesions: Diagnostic value of qualitative and quantitative diffusion weighted MR imaging.

2016 | Keywords Focal live lesions (FLLs), Diffusion weighted imaging (DW, Apparent diffusion coefficient,
Benign versus malignant focal liver lesions: Diagnostic value of qualitative and quantitative diffusion weighted MR imaging.
BACKGROUND AND OBJECTIVE: Diffusion-weighted imaging has an emerging role for assessment of focal and diffuse liver diseases. The aim of this study was to evaluate the diagnostic performance of DWI for characterization of focal liver lesions (FLLs). PATIENTS AND METHODS: This prospective study included 40 consecutive patients with 64 focal liver lesions, who underwent MRI of the liver. All patients ... Read more

Intraobserver and intermethod reliability for using two different computer programs in preoperative lower limb alignment analysis

2016 | Keywords Lower limb alignment, Computer programs analysis,
Intraobserver and intermethod reliability for using two different computer programs in preoperative lower limb alignment analysis
BACKGROUND AND OBJECTIVE: Professional graphics editing programs can be used in the preoperative planning of lower limb deformity correction surgery. This study was conducted ton test the reliability of using such programs versus FDA approved medical planning software. MATERIALS AND METHODS: Thirty long standing lower limb radiographs had been selected. Two different computer programs (Adobe Photoshop) versus planning software (MediCAD) ... Read more

2015 | Keywords MRI, Adult, Stiff elbow,
Stiff elbow in adult: MR imaging findings
OBJECTIVE: To elucidate the MRI findings of stiff elbow in adult and determine their values in the preoperative diagnosis of the mechanism of stiffness. PATIENTS AND METHODS: This prospective study included MR images of 39 stiff elbow joints in 36 nonconsecutive patients referred to MRI unit in Diagnostic Radiology Department at Sohag University Hospital between October 2011 and December 2014. ...

Assessment of the diagnostic reliability of brain CT and MRI in pediatric epilepsy patients

2015 | Keywords Pediatric epilepsy, CT, MRI,
Assessment of the diagnostic reliability of brain CT and MRI in pediatric epilepsy patients
OBJECTIVE: Analysis of the role of CT and MRI in evaluation of pediatric epilepsy and their diagnostic utility to detect various pathologic entities at one center. PATIENTS AND METHODS: From April 2012 to April 2014, 181 children with epilepsy were underwent standardized CT and or MRI in the Department of Diagnostic Radiology at Sohag University Hospitals. We retrospectively analyzed whether ... Read more

Pedicle involvement in tuberculous spondylitis and pyogenic spondylitis: Comparative magnetic resonance imaging study

2014 | Keywords Tuberculous spondylitis, Pyogenic spondylitis, Pedicle involvement, MRI,
Pedicle involvement in tuberculous spondylitis and pyogenic spondylitis: Comparative magnetic resonance imaging study
AIM: Magnetic resonance imaging (MRI) comparison of the pedicle involvement in TB spondylitis and pyogenic spondylitis in relation to degree of spinal deformity, degree of vertebral body and disc damage and paravertebral and epidural abscess formation MATERIALS AND METHODS: MRIs of 38 patients who had been diagnosed with and treated for spinal infection, 22 patients for TB spondylitis and 16 ...

MRI evaluation of TMJ internal derangement: Degree of anterior disc displacement correlated with other TMJ soft tissue and osseous abnormalities

2014 | Keywords MRI, TMJ dysfunction, Anterior disc displacement,
MRI evaluation of TMJ internal derangement: Degree of anterior disc displacement correlated with other TMJ soft tissue and osseous abnormalities
OBJECTIVE: To evaluate the relationship between anterior disc displacement (ADD) degree and other temporomandibular joint (TMJ) soft tissues and osseous abnormalities in symptomatic TMJ dysfunction based on magnetic resonance imaging findings. PATIENTS AND METHODS: MR images of 106 TMJs in 53 patients, presented with symptomatic TMJ dysfunction were included. Degree of ADD was detected and its relationship to joint effusion, ... Read more

Sensitivity, Specificity and Accuracy of Magnetic Resonance Imaging for Differentiating Vertebral Compression Fractures Caused by Malignancy, Osteoporosis, and Infections

2011 | Keywords fractures, , fractures, compression;, infection;, Magnetic, neoplasm metastasis, osteoporosis;, spinal fractures,
Sensitivity, Specificity and Accuracy of Magnetic Resonance Imaging for Differentiating Vertebral Compression Fractures Caused by Malignancy, Osteoporosis, and Infections
PURPOSE: To evaluate the sensitivity, specificity and accuracy of various magnetic resonance imaging (MRI) features in differentiating vertebral compression fractures caused by malignancy, osteoporosis, and infections. METHODS: 35 men and 45 women aged 40 to 78 (mean, 59) years underwent MRI to assess the underlying pathology of already diagnosed vertebral compression fractures (n=152). The interval from presentation to imaging ranged ... Read more
