Siemens Healthineers Introduces GOKnee3D MR Application

Novel application reduces scan time for MR imaging of the knee from 20 minutes to 10, enables clinically validated, high-resolution isotropic 3-D knee exam with all relevant contrasts and evaluation in all imaging planes

Siemens Healthineers Introduces GOKnee3D MR Application

November 27, 2017 — At the 103rd Scientific Assembly and Annual Meeting of the Radiological Society of North America (RSNA), Siemens Healthineers debuted GOKnee3D, a magnetic resonance imaging (MRI) application that drastically shortens the time required to perform comprehensive diagnostic exams of the knee. Currently, a typical knee examination can be roughly 20 minutes. GOKnee3D enables a push-button, high-resolution diagnostic 3-D knee exam in just 10 minutes. The acquisition of high-resolution isotropic 3-D images subsequently allows flexible evaluation of the images in all possible planes, including double oblique and curved planar. Increasing MRI efficiency in this manner is especially important because knee examinations are the third most common type of MRI examination, accounting for 11 percent of all scans.

The volume acquisition of GOKnee3D is based on a CAIPIRINHA SPACE protocol, which enables higher scan speeds and optimal image reconstruction with better signal quality than in previous technologies. Supported by dedicated, high-channel knee coils as well as automated field-of-view adaptation based on machine learning and artificial intelligence, the MR scanner acquires the volume data of the knee joint at the touch of a button.

To develop and clinically validate the technique, Siemens Healthineers collaborated with Johns Hopkins University in Baltimore. “GOKnee3D enables comprehensive evaluation of internal derangement to the knee,” said Jan Fritz, M.D., assistant professor of radiology and radiological sciences at the Johns Hopkins University School of Medicine. “The fully automated CAIPIRINHA SPACE protocol provides high-quality MR imaging in 10 minutes and ensures consistency of image quality and operational efficiency. The high spatial resolution isotropic data sets help to visualize abnormalities with high accuracy, enable reformations of virtually any imaging plane, and create high-quality 3-D-rendered MR images.”

GOKnee3D is U.S. Food and Drug Administration (FDA) 510(k)-pending. It is available as an upgrade for the Magnetom Skyra 3T and Magnetom Aera 1.5T MR scanners, with eventual rollout planned for additional MR scanners.

Early diagnosis of cancer is one of the highest-priority problem for the healthcare system, because it is critical for overall treatment success and saving patients' lives. Diffusion-weighted magnetic resonance imaging (DWI) may be used to detect a malignancy in various tissues and organs. It has the advantage of providing insight into the diffusion of water molecules in body tissues without exposing patients to radiation.

Researchers from Tokyo Metropolitan University have surveyed the amount of gadolinium found in river water in Tokyo. Gadolinium is contained in contrast agents given to patients undergoing medical magnetic resonance imaging (MRI) scans, and it has been shown in labs to become toxic when exposed to ultraviolet rays. The researchers found significantly elevated levels, particularly near water treatment plants, highlighting the need for new public policy and removal technologies as MRI become even more commonp

Experimental Protocol and Representative MRI of Brains at Various Key Points in That Protocol.

Experimental Protocol and Representative MRI of Brains at Various Key Points in That Protocol. (A) Experimental timeline. (B) Representative T2WI (using an 11.7T MRI) of the brain of a postnatal day (PND) 11 pup, 1 day after inducing left HII and prior to hNSC transplantation. Note the beginning of an increasingly intense “water signal” (white) on the left (“HII lesion”). (C) Representative T2WI (using an 11.7T MRI) 3 days post-HII, shortly after implantation of SPIO pre-labeled hNSCs into the contralateral cerebral ventricle (“Lateral Vent”). Note the “HII lesion” on the left becoming hyperintense (white) and the black signal void of the SPIO-labeled hNSCs in the lateral ventricle (black arrow). Red arrows denote the needle track. In contrast to what occurs in the intact brain (Figure S4), in a brain subjected to left HII, the implanted SPIO-labeled hNSCs (black signal void) (black arrow) migrate from the right (“R”) to the left (“L”) hemisphere to enter the lesion. (D and E) Shown here (using a 4.7T MRI) are SPIO-labeled hNSCs (black signal void) (black arrow) at 1 month post-implantation into the contralateral ventricle (D) and, in the same representative animal, at 3 months post-implantation (E)–stably integrated and surrounding a much-reduced residual lesion, with no interval enlargement of the graft or ventricles.

There was generalized small bowel distension and segmental thickening (arrows), with adjacent mesenteric congestion (thin arrow in B), and a small volume of ascites (* in B). Findings are nonspecific but suggestive of early ischemia or infection.
