New method would allow doctors to detect earliest stages of cancers in the lymph nodes

The vast majority of cancer deaths occur due to the spread of cancer from one organ to another, which can happen either through the blood or the lymphatic system. However, it can be tricky to detect this early enough.

Cancer imaging technique can help detect preeclampsia in pregnancy

An imaging technique used to detect some forms of cancer can also help detect preeclampsia in pregnancy before it becomes a life-threatening condition, a new Tulane study says.

PET imaging better detects coronary artery disease than SPECT scans

Patients who receive cardiac positron emission testing (PET) imaging instead of single photon emission computed tomography scan experienced a significant increase in the detection of severe obstructive coronary artery disease, according to researchers at the Intermountain Medical Center Heart Institute in Salt Lake City.

New imaging technology could help find tiny tumors

Many types of cancer could be more easily treated if they were detected at an earlier stage. MIT researchers have now developed an imaging system, named "DOLPHIN," which could enable them to find tiny tumors, as small as a couple of hundred cells, deep within the body.

Breakthrough software tool tracks activity of neurons in real time

Tracking the firings of individual neurons is like trying to discern who is saying what in a football stadium full of screaming fans. Until recently, neuroscientists have had to tediously track each neuron by hand.

Novel MRI sensor can peer deep into the brain to detect intracellular calcium activity

Calcium is a critical signaling molecule for most cells, and it is especially important in neurons. Imaging calcium in brain cells can reveal how neurons communicate with each other; however, current imaging techniques can only penetrate a few millimeters into the brain.

Movement of wrist bones revealed by MRI and computer modeling

We use our wrists constantly, but how do they work? In a just-published Journal of Biomechanics article, the researchers proved a longtime assumption about individuals' right and left wrists, while also finding differences between wrists of males and females: discoveries that could help inform and guide future treatments.

A new step in decoding cell-to-cell communication

Cells in our bodies have the ability to speak with one another much like humans do. This communication allows organs in our bodies to work synchronously, which in turn, enables us to perform the remarkable range of tasks we meet on a daily basis.

Reviewing applications of advanced materials in drug delivery and biomedicine

The Graphene family of materials has emerged as one of the most useful new age nano-biomaterials. Graphene-based materials exhibit excellent physicochemical properties, such as high electrical conductivity, mechanical strength, and high surface area with π-conjugated carbon atoms stacked to form honeycomb structure, suitable for binding other molecules.
