Columbia University has quietly suspended research at a nationally prominent brain-imaging center and reassigned its top managers after federal investigators found that it had routinely injected mental patients with drugs that contained potentially dangerous impurities.
In April, a group of nine medical specialty boards recommended that doctors perform 45 common tests and procedures less often, with imaging prominent among them.
Pre-sacral soft tissue thickening may also be a normal post-operative finding and should remain stable or become less prominent on subsequent imaging.
It is notable that regions in which amyloid deposition tends to be prominent from PIB imaging data (prefrontal, gyrus rectus, precuneus, lateral temporal) are not areas in which prominent thinning is found.
Another explanation might be that amygdala is affected later in the disease process of Alzheimer's disease than the hippocampus, the putamen and thalamus, and therefore not prominent in MR imaging of patients that attended the memory clinic for the first time.
Ultrasound or sonography is widely used in medicine, and has several advantages compared to other prominent methods of imaging including portability, low cost, the absence of harmful ionizing radiation, the provision of images in real-time, no discomfort or long-term side effects to the participant, and widely available equipment.
By exploiting the sparsity of the phase images, which is prominent in many biological imaging applications, and modeling of the image formation via complex fields, the very fine structures can be recovered which were blurred by the optics.
The present case showed prominent calcification in preoperative imaging and the excised mass mostly consisted of calcification with scattered tumor cells.
Results obtained using microphone and high speed imaging, show prominent reductions in the amplitudes of the first mode of the thermoacoustically unstable flame, with increased rotation rate of the swirler.
