Blood test may help signal tumor's remission, return in throat cancer patients

...er. Clinical exams, X-rays, and magnetic resonance imaging (MRI) are currently used to monitor a patient’s progress, but observation by these methods has been difficult due to the scarring that occurs from radiation. “Finding better markers for detecting cancer as it begins and then monitoring the course ...

Researchers track how spores break out of dormant state

...- to 3- nm-wide fibrils remained. The in vitro AFM imaging also revealed the porous fibrous cell wall structure of newly emerging and mature vegetative cells, consisting of a network of nanometer-wide peptidoglycan fibers. “These results show that dynamic AFM is a promising tool to investigate the formation ...

...c of UPMC, will discuss the emerging role of brain imaging techniques in psychiatry in general as well as in .... Phillips also will present data illustrating how imaging can be used to identify biomarkers and how these markers can help clinicians determine which patient...

Brightening prospects of using fluorescent nanotubes in medical applications

...for months. Fluorescent proteins – widely used for imaging living systems – begin fading within a few hours. Quantum dots last several days before degrading. Hertel’s team is currently working on the next step necessary for many biomedical uses: finding a way to attach molecules to the surface of the nano...

Clot-dissolving agent may be beneficial in treatment of severe frostbite

... who were admitted with severe frostbite underwent imaging studies to assess blood flow to the affected limb. From 2001 to 2006, six patients with abnormal blood flow on angiography received tPA within 24 hours of severe frostbite injury. These individuals were compared with 25 frostbite patients treated fro...

3-D ultrasound scanner provides in-depth view of the brain

...en computed tomography (CT) and magnetic resonance imaging (MRI) equipment is unavailable, the researchers sa...evelopment of a 3-D ultrasound device designed for imaging the heart and other internal organs during endoscopic surgeries performed through tiny "keyhole" inc...

Surprising origin of cell's internal highways

...this was impossible before the advent of live-cell imaging techniques that could reveal the true origins of these structures. "The Golgi apparatus is very close to the centrosome," said Kaverina. "So if you're not looking at it precisely, it is hard to distinguish between the centrosome and Golgi." T...

'Virtual autopsy' helps identify drowning as cause of death

...ss casualty scenarios. "More and more, advanced imaging tools such as MDCT are being applied to forensic investigations," Dr. Levy said. "In the future, imaging in forensics may be just as important as imaging in clinical medicine."...

Researchers use MRI to predict recovery after spinal cord injury

Using magnetic resonance imaging (MRI), radiologists can better predict the likelih...injury. The research team studied three measurable imaging parameters: maximum spinal cord compression (MSCC), maximum canal compromise (MCC) and length of les...

Focused ultrasound relieves fibroid symptoms in women

...atic fibroids. The women received pre-treatment MR imaging to identify and define the target fibroids. Radiologists then used MRgFUS to locate and treat the targeted fibroids while monitoring temperature changes in tissue. Ninety-six patients were treated under the original study protocol (A), and 64 pa...

Better insight into brain anatomical structures

Magnetic resonance imaging is a very effective method for revealing anatomical details of soft tissues. Contrast agents can help to make these images even clearer and allow physiological processes to be followed in real time. Conventional gadolinium complexes currently used as...

'Virtual Patient' to simulate real-time organ motions for radiation therapy

... heart is a main concern in radiation treatment or imaging of tumors that are affected by such organ movement," Xu said. "In order to determine accurate and effective radiation dosages, doctors must consider such issues as the breathing function and air volume change that are affected by several physiologica...
