This study aimed to assess the diagnostic performance of integrated positron emission tomography (PET)/magnetic resonance imaging (MRI) breast for lesion detection and local tumor staging patients with primary cancer in comparison PET/computed (CT) MRI.The was approved by institutional review board. Forty-nine biopsy-proven invasive were prospectively enrolled our study. All underwent a PET/CT, subsequently, contrast-enhanced PET/MRI after written informed consent obtained before each...
Objective: The purpose of this study was to assess the diagnostic value and safety contrast agent gadoterate meglumine (Gd-DOTA, DOTAREM, Guerbet, Roissy CdG Cedex, France) in setting a postmarketing surveillance study. Materials Methods: Between January 2004 October 2005, radiologists 61 radiologic institutions were asked document routine use Gd-DOTA questionnaire. In addition assessing image quality contrast-enhanced magnetic resonance imaging scans, we statistically evaluated analyzed...
The objective of this study was to assess the diagnostic value integrated positron emission tomography/magnetic resonance imaging (PET/MRI) for whole-body staging patients with recurrent gynecological pelvic malignancies, in comparison MRI alone.The approved by local institutional ethics committee. Written informed consent obtained before each examination. Thirty-four consecutive a suspected recurrence cervical (n = 18) or ovarian 16) cancer were prospectively enrolled an PET/MRI...
The aim of this study was to assess the diagnostic benefit diffusion-weighted imaging (DWI) in an (18)F-FDG PET/MR protocol for whole-body staging women with primary or recurrent malignancies pelvis.Forty-eight patients a pelvic malignancy suspected recurrence were included our study. All underwent examination that DWI. Two radiologists separately evaluated datasets without DWI followed by second interpretation First, both readers identified all tumors, as well lymph node and distant...
Appendicitis is frequently diagnosed in the emergency department, most commonly using CT. The purpose of this study was to compare diagnostic accuracy contrast-enhanced MRI with that CT for diagnosis appendicitis adolescents when interpreted by abdominal radiologists and pediatric radiologists.Our included a prospectively enrolled cohort 48 patients (12-20 years old) nontraumatic pain who underwent MRI. Fellowship-trained reviewed all studies randomized order, blinded patient outcome....
With the successful implementation of ultra-high-field imaging in neuro- and musculoskeletal imaging, interest scientific research expanded toward whole-body applications. The aim this study was to assess feasibility dynamic contrast-enhanced renal magnetic resonance (MRI) at 7 Tesla (T), with optimization a dedicated examination protocol.In vivo high-field examinations were obtained 10 healthy subjects on T MR scanner. A custom-built body transmit/receive reduced radiofrequency (RF) coil...
To evaluate the diagnostic performance of T2-weighted magnetic resonance (MR) cholangiopancreatography pulse sequences in comparison with MR combined nonenhanced T1-weighted images detection biliary cast syndrome liver transplant recipients.This retrospective study was conducted accordance declaration Helsinki. Institutional review board approval obtained. 95 patients who were examined after transplantation and presented symptoms obstruction examined. Two separate sets images,...
Assessment of motility alterations by functional magnetic resonance imaging (MRI) contributes to improved evaluation inflammatory bowel disease. The aim the study was quantify in segments and compare with MR-based parameters for activity inflammation Crohn's disease (CD).Thirty consecutive patients CD underwent MRI which included a dynamic sequence automatic generation parametric maps facilitating quantification motility. Mean score (MMS) small signs measured compared MMS whole...
Purpose To develop and implement an automated algorithm for visualizing quantifying bowel motility using cine magnetic resonance imaging (MRI). Materials Methods Four healthy volunteers as well eight patients with suspected or diagnosed inflammatory disease (IBD) underwent MR examinations on a 1.5T scanner. Coronal T2‐weighted images were acquired in without intravenous (i.v.) administration of butylscopolamine. In IBD, MRI sequences collected prior to standard MRI. Bowel was assessed...
This study aims to develop, implement, and evaluate a 16-channel radiofrequency (RF) coil for integrated positron emission tomography/magnetic resonance (PET/MR) imaging of breast cancer. The RF is designed optimized MR performance PET transparency attenuation correction (AC) applied accurate quantification.A array was PET/MR hybrid cancer lesions. features lightweight rigid design positioned with spacer at defined position on the patient table an system. Attenuation performed by generating...
The objective of this study was to evaluate whether the use automatically generated maps bowel motility (motility mapping) in magnetic resonance imaging (MRI) leads an increased detection rate inflammatory disease.Fifty consecutive patients with suspected or known disease who underwent MRI using a 1.5-T scanner were analyzed retrospectively. In addition standard small protocol, dynamic coronal T2-weighted sequence (dynamic MRI) acquired. Dynamic sequences used generate parametric map...
Magnetic resonance colonography (MRC) is a well-accepted, noninvasive imaging modality for the depiction of inflammatory bowel disease. Diffusion-weighted (DWI) very helpful to display lesions. The aim this retrospective study was assess whether intravenous contrast needed depict lesions in magnetic if DWI available.Thirty-seven patients (23 females, 14 males; mean age, 14.6 years) underwent MRC on 1.5-T scanner (MAGNETOM Avanto; Siemens). Contrast-enhanced T1-weighted (ce-T1-w) sequences...
To investigate the feasibility of 7 Tesla (T) nonenhanced high field MR imaging renal vasculature and to evaluate diagnostic potential various T1-weighted (T1w) sequences.Twelve healthy volunteers were examined on a 7T whole-body system (Magnetom 7T, Siemens Healthcare Sector) using custom-built eight-channel radiofrequency (RF) transmit/receive body coil. Subsequent RF shimming, following sequences acquired (i) fat-saturated two-dimensional (2D) FLASH, (ii) 3D (iii) 2D time-of-flight...
