PhotoAcoustic Imaging

PhotoAcoustic imaging is an imaging modality that uses laser light and ultrasound detectors to image tissues. Photo = Light. Acoustic = Sound. The imaging uses the photoacoustic effect principle. The photoacoustic effect is not new in terms of discovery as it was reported by none other than Alexander Graham Bell (yes! Rings a bell doesn’t it?) as early as 1880. But, the unavailability of proper detectors and instruments at his time was an obstacle to expanding research in this field.

 

Glucose Monitor

Diabetes prevalence is rapidly increasing in the world. The number of people with diabetes has risen from 108 million in 1980 to 422 million in 2014. Considering the size of the problem, you must all have seen or maybe used a glucose monitor. So, how does it work?

Blood glucose level is kept in check in the body by a hormone called insulin, produced by the pancreas. Unstable insulin levels in blood may cause excess glucose to be converted to fat and be deposited on your blood vessels as plaque. This may cause various complications such as cardio-vascular disease, nerve damage, kidney damage, eye damage among a lot of other complications.

Fitness trackers..Do they really track?

Most often, people use Fitness trackers for keeping track of their fitness activity, set achievable goals and to motivate themselves. Fitness trackers are mostly wearable electronics that measure/track your activity such as steps taken, distance walked, calorie consumption and even heart rate in some cases. Most fitness trackers have an accelerometer that helps in tracking our activity. Some fitness trackers may also have altimeter, music player and many other features. So, how does the fitness tracker do it?

Radio-Pharmaceuticals

Radiotracers are chemical compounds that are used to diagnose or deliver therapy to specific organs and tissues. The radiotracer consists of a linking molecule, a binding molecule and a radioactive compound. Radiotracer is injected into the body and it binds to specific target cells in the body. The linking molecule binds the radioactive compound to the binding molecule, which then binds to specific cells in body.

The radiotracer decays by emitting ionizing radiation that damages nuclear DNA, thereby stopping division of cells (cancer as well as normal cells). Radiotracers are not something new. In fact, they have been around for 100 years !!

Introduction to Theranostics

Introduction to Theranostics

Theranostics is a field of medicine that refers to a combination of diagnostic imaging and therapy to treat various types of cancers. Theranostics = Therapy + Diagnostics. Patients are imaged and depending on the tumour size and spread, are identified for therapy. The therapy is given by localized radiation delivered only to the diseased region, reducing the impact on surrounding healthy cells.

Principle of Theranostics

How does it work?

  • Radioactive compound is attached to a linking molecule that is bound to the binding molecule, which attaches to the cancer cell.
