TT-TG Distance Suggest That The Kneecap Is Off Center

The study find that the John Vairo, clinical associate professor of kinesiology, orthopedics and rehabilitation, said that ideally, a person’s kneecap will align with the midline of the leg neither too far to the left or the right. A greater TT-TG distance may suggest that the kneecap is off center and therefore more likely to…

Dose Reduction In Brain [18F]FDG PET/MRI

Positron emission tomography (PET) has been use for neurological imaging for decades. 2-Deoxy-2-[18F]fluoro-Dglucose ([18F]FDG) remains the main radio pharmaceutical agent used for patients with suspected neurodegenerative dementia. In the 2009 guidelines for brain PET/MR imaging studies; the European Association of Nuclear Medicine recommended the injection of 125 to 250 MBq. The Society of Nuclear Medicine…

PET/ MRI Platform To Track Small Extracellular Vesicles

The researches find that the a two-step surface modification methodology to radiolabel small extracellular vesicles (SEVs) with 64CuCl2 for PET/MRI imaging. The modification did not change or damage the morphology, surface receptor proteins and internal RNA content. Radiolabeled SEVs  detect in organs with low accumulation such as the brain (0.4-0.5% ID/g) and their brain location…

MRI Diffuse Weighted Imaging Combined With PET/CT

MRI diffusion-weighted imaging (MRI DWI) combined with PET/CT in the diagnosis and staging of stomach cancer (SC) was investigated. A retrospective analysis was performed on 160 patients with SC diagnosed by pathological biopsy in The Affiliated Yantai Yuhuangding Hospital of Qingdao University . The values of MRI DWI; PET/CT and combin diagnosis in the diagnosis…

Simultaneous PET/MRI in the Evaluation of Breast and Prostate Cancer

The researches find that the The performance of sodium 18F]fluoride (Na[18F]F)/2-deoxy-2-[18F]fluoro-D-glucose ([18F]FDG) simultaneous time-of-flight enabled positron emission tomography (PET)/magnetic resonance imaging (MRI) for the detection of skeletal metastases in selected patients with advanced breast and prostate cancers. Therefore Procedure: The institutional review board approved this HIPAA-compliant protocol. Written inform consent is obtain from each patient.…

Multiparametric 18F-FDG PET-MRI of the Breast

To assess whether there are differences in multiparametric 18Ffluorodeoxyglucose positron emission tomography–magnetic resonance imaging (18FFDG PET-MRI) biomarkers of contralateral healthy breast tissue in patients with benign and malignant breast tumors. In this IRB-approved prospective single-institution study, 141 women with imaging abnormalities on mammography or sonography (BI-RADS 4/5) underwent combined 18F-FDG PET-MRI of the breast at…

3D Printed Models May Best CT/MRI for Renal Tumor

The researches find that the Experienced surgeons had trouble identifying the locations of kidney tumors on 3-dimensional models based only on information from typical 2-dimensional preoperative imaging; but a new study found. The authors say 3D models could improve surgical planning. “Typically; when planning for surgical procedures, surgeons rely on CT and MR imaging data,”…

Blood Flow Quantification with 82Rubidium PET/CT in Prostate Cancer

The study find that the prostate TBF measurement with the widely used positron emission tomography (PET) flow tracer 82Rubidium (82Rb). However, no test-retest data is available for TBF measurement with 82Rb PET in prostate cancer. Such information is important to determine the potential clinical usefulness of the technique. The aim of the present study was to…

Hybrid PET/MRI in Major Cancers: a Scoping Review

The researches find that the the introduction of clinical FDG PET/CT about two decades ago, its use in patient treatment has increased dramatically and is now well established. Being a whole-body molecular imaging modality; FDG PET/CT plays an important role in most cancers and is use for staging, treatment planning, recurrence detection; and lately also…

MRI and PET/MRI in Hematologic Malignancies

The role of MRI differs considerably between the three main groups of hematological malignancies: lymphoma, leukemia, and myeloma. In myeloma; whole-body MRI (WB-MRI) is recognize as a highly sensitive test for the assessment of myeloma, and is also endorse by clinical guidelines, especially for detection and staging. In lymphoma, WB-MRI is presentlynot recommended; and merely…

Cancer Using 68Ga-PSMA PET/CT Compared with mpMRI

The researches find that the To compare the accuracy of 68Gallium prostate-specific membrane antigen positron emission tomography/computed tomography; (68Ga-PSMA PET/CT) with mpMRI in detecting and localising primary prostate cancer when compared with radical prostatectomy (RP) pathology. Therefore Retrospective review of men who underwent 68Ga-PSMA PET/CT and mpMRI for primary prostate cancer prior to RP across…
