Scoliosis is defined as a lateral spinal curvature with Cobb angle of 10° or more. This abnormal may be the result an underlying congenital developmental osseous neurologic abnormality, but in most cases cause unknown. Imaging modalities such radiography, computed tomography (CT), and magnetic resonance (MR) imaging play pivotal roles diagnosis, monitoring, management scoliosis, radiography having primary role MR CT indicated when presence suspected. In interpreting features it essential to...

The aim of our study was to compare the efficacy multidetector row computed tomography (MDCT) with magnetic resonance imaging (MRI) and fluorodeoxyglucose-positron emission (FDG-PET) for detection spinal bone marrow involvement in patients multiple myeloma.Ten myeloma stage III underwent MDCT MRI spine FDG-PET. number location lesions detected by 3 modalities were recorded, a lesion-by-lesion analysis completed, using McNemar test. For MDCT, image performed according type lesion (established...

Objective: To assess whether multi-echo Dixon magnetic resonance (MR) imaging with simultaneous T2* estimation and correction yields more accurate fat-signal fraction (FF) measurement of the lumbar paravertebral muscles, in comparison non-T2*-corrected two-echo or T2*-corrected three-echo Dixon, using FF measurements from single-voxel MR spectroscopy as reference standard.Materials Methods: Sixty patients low back pain underwent a 1.5T scanner.FF mapping images automatically obtained...

Objective: To assess the feasibility of T2*-corrected fat-signal fraction (FF) map by using three-echo volume interpolated breath-hold gradient echo (VIBE) Dixon sequence to differentiate between malignant marrow-replacing lesions and benign red marrow deposition vertebrae. Materials Methods:We assessed 32 from patients who underwent magnetic resonance imaging after being referred for assessment a known or possible vertebral abnormality.The were divided into 21 11 depositions.Three sequences...

Background: The presence and extent of osteolytic bone lesions in untreated patients with multiple myeloma are important factors the staging disease, cases significantly influences decisions regarding therapy. Recently, fluorodeoxyglucose positron emission tomography (FDG-PET) magnetic resonance imaging (MRI) have been used to detect marrow involvement myeloma. Purpose: To compare efficacy FDG-PET MRI for detection infiltration into spine Material Methods: Twenty-two underwent both MRI....

Objective: To assess the performance of diffusion tensor imaging (DTI) for diagnosis cervical spondylotic myelopathy (CSM) in patients with deformed spinal cord but otherwise unremarkable conventional magnetic resonance (MRI) findings.Materials and Methods: A total 33 who underwent MRI spine including DTI using twodimensional single-shot interleaved multi-section inner volume diffusion-weighted echo-planar whose cords were showed no signal changes on subjects this study.Mean diffusivity...

Objective: To investigate the validity of 100 kVp setting in CT venography (CTV) diagnosis deep vein thrombosis (DVT), and to evaluate feasibility reducing amount administered iodine this setting.Materials Methods: After receiving contrast medium (CM) 2.0 mL/kg, 88 patients underwent CTV pelvis lower extremities by using one four protocols: Group A, 120 370 mgI/mL CM; group B, 300 mgI/mL; C, D, mgI/mL.The groups were evaluated for venous attenuation, vein-to-muscle contrast-to-noise ratio...

To develop a diagnostic model for superficial soft tissue lesions to differentiate epidermal cyst (EC) from other based on ultrasound (US) features.This retrospective study included 205 patients who had undergone US examinations and subsequent surgical excision. The population was divided into the derivation set (n = 112) validation 93) according imaging date. following features were analyzed determine those that could discriminate EC lesions: more-than-half-depth involvement of dermal...

Objective: Clear depiction of the common bile duct is important when evaluating neonatal cholestasis in order to differentiate biliary atresia from other diseases.During MR cholangiopancreatography, T2-shortening effect gadolinium can increase contrast-to-noise ratio (CNR) and enhance its depiction.The purpose this study was confirm, by performing a phantom study, gadolinium, evaluate different chelates with concentrations magnetic field strengths for investigating optimal combination these...

Background: Analysis of serum biomarkers and magnetic resonance spectroscopy (MRS) are useful for monitoring disease progression in patients with mitochondrial encephalomyopathy, lactic acidosis, stroke-like episodes (MELAS). We evaluated the correlation MRS parameters during changes associated episodes. Methods: In 13 symptomatic MELAS carrying A3243G mutation, we retrospectively obtained 207 voxels from 41 studies, which were divided into three groups according to temporal association The...

Magnetic resonance (MR) imaging and measurement of glycosaminoglycan (GAG) have potential for characterization hyaline articular cartilage. Recently, some reports demonstrated the direct administration contrast media MR cartilage.To prove feasibility intraarticular gadolinium-enhanced cartilage (iGEMRIC) T1 relaxation mapping in vivo with injection Gd-DTPA2-.Five healthy beagle dogs underwent knee joints both hind legs. The delayed (dGEMRIC) iGEMRIC techniques were interchanged imaging. For...

Skeletal muscle metastasis is a rare condition in renal cell carcinoma (RCC). We here present an extremely case of late recurrence patient with RCC who had multiple metastases 19 years after radical nephrectomy. This shows that soft-tissue mass known history even curative nephrectomy, particularly hypervascularity, must be regarded as highly suspicious skeletal metastasis.

In this study, we aimed to develop a new automated method for kidney volume measurement in children using ultrasonography (US) with image pre-processing and hybrid learning formulate an equation calculate the expected volume. The volumes of 282 kidneys (141 subjects, <19 years old) normal function structure were measured US. 58 29 subjects who underwent US computed tomography (CT) determined by segmentation compared those calculated conventional ellipsoidal CT intraclass correlation...

Purpose: The aim of this study was to compare the accuracy fluorodeoxyglucose-positron emission tomography (FDG-PET) with bone scan for diagnosis single metastasis using a semiquantitative method. Material and Methods: Seventy-six patients suspected metastasis, who underwent both FDG-PET scan, were selected. number location lesions detected upon recorded, compared McNemar test. For analysis, maximum (max) standard uptake value (SUV) 2.5 used as positive cutoff metastasis. difference in max...

To evaluate the differences between shear wave velocities (SWVs) measured with ultrasound elastography during continuous motion using liver fibrosis phantoms.Elasticities were convex and linear transducers of supersonic imaging (SSI) acoustic radiation force impulse (ARFI) elasticity phantoms (3.0 16.9 kPa) at depths 2, 3, 4, 5 cm.
