Cutting-Edge Diagnostic Tools

Stealth Navigation (S8) System

The S8 Stealth Navigation System is a technology used to generate 3D models of tumors, white matter tracts, the cortical surface or the vessels. These 3D models are useful to help visualise the structures in the brain quickly and help plan surgical approaches more accurately. The tool integrates seamlessly with imaging diagnostics to develop models, saving time and increasing the chances of a good outcome.

Advanced Surgical Microscopes

Our surgical suites are equipped with advanced surgical microscopes, geared to take on the challenges of microsurgery. Advanced surgical microscopes produce sharp, detailed, highly-magnified images of the surgical field. Surgeons typically operate on patients while viewing the surgical field through an advanced surgical microscope in real-time. The microscope facilitates long reach, high manoeuvrability and flexible viewing options.

Cavitron Ultrasonic Aspirator (CUSA)

A Cavitron ultrasonic aspirator is a tool used by neurosurgeons to cut out brain tumours without affecting the surrounding healthy tissue. The Cavitron ultrasonic aspirator probe is inserted into the tissue with an irrigator and an aspirator to vacuum suction out the tissue debris generated. The device generates ultrasonic waves at about 23 kHz to fragment the tumour tissue.

CRW Stereotactic Equipment

Stereotactic Equipment is used to perform minimally-invasive brain surgery. The system works by creating a 3D co-ordinate system to locate small targets inside the brain, and ablate, biopsy, or stimulate the mass. This co-ordinate system is created by setting up a reliable frame of reference in the body, using prominent landmarks such as bones, which bear a constant spatial relationship to the soft tissues.

Transcranial Doppler

A Transcranial Doppler is a type of doppler ultrasound scan that measures the velocity of blood flowing through the vessels in the brain. This scan can be used to diagnose emboli, stenosis, and other brain conditions. Transcranial Doppler scans are useful because they are a low-cost, non-invasive, painless method of assessing cerebral haemodynamics, brain anatomy and intracranial lesions.

Intracranial Pressure Monitoring Equipment

Intracranial pressure monitoring equipment is used to measure the pressure exerted on the skull. If the brain swells and intracranial pressure increases beyond a certain limit, it could lead to permanent brain damage. Intracranial pressure is measured in two ways – It can be measured using a hollow catheter, or a hollow bolt. The catheter is placed into the fluid-filled void in the lateral ventricle of the brain to check the pressure of the cerebrospinal fluid.. Alternatively, the surgeon could use the subdural bolt method. In this method of intracranial pressure monitoring, a hollow screw is drilled through the skull into the subdural space. In both cases, the device is inserted by a surgeon in the Intensive Care Unit (ICU) or the Operating Room. The patient will be medicated while the monitoring equipment is inserted, to keep them comfortable. The probe is removed once swelling decreases and is deemed unlikely to recur.

Intraoperative Neuromonitoring (Brain Mapping)

Intraoperative Neuromonitoring techniques are used during high-risk surgeries to monitor the responsiveness of the neural networks. They are also used to map the structures of the nervous system for diagnostic purposes. Intraoperative neuromonitoring is used to shrink tumours which have spread through the brain and do not have defined edges. The patient may be sedated at the beginning and end of the procedure; however, in the middle, while the patient’s brain is being stimulated with electrodes, they will be required to be awake and perform basic tasks such as talking, counting, or identifying images. This is required to precisely locate the functional areas of the brain that must be protected. The patient’s vitals are constantly monitored during the procedure and they are kept calm with verbal reassurance.


3 Tesla MRI/ Functional MRI

Functional Magnetic Resonance Imaging (fMRI) is a safe, non-invasive technique used for measuring and mapping brain activity. The functional MRI device measures brain activity by detecting changes in blood flow. It functions on the principle that when an area of the brain is active, blood flow to that region increases. During the procedure, the patient lies on their back on the flat bed of the fMRI machine. The bed is then rolled into the hollow cylinder of the device. The procedure typically lasts about 40-50 mins, with the doctors in the adjacent control room, viewing the patient through the glass window. The doctors will instruct the patient to do silent brain exercises while lying completely still in the fMRI machine.

Diffusion Tensor Imaging

Diffusion Tensor Imaging is an MRI technique that measures the directional movement of water molecules in tissues. The technique is used to locate the white matter tracts in the brain, in order to avoid damaging them during surgery. The patient lies on the flatbed of an MRI device and is rolled into the hollow cylinder.

CT Angiography

A CT Angiography is a medical imaging test used to detect abnormalities in the blood, like clots, aneurysms and atherosclerosis. During the CT angiography, the patient is placed in the CT device, and a dye is injected into the part of the body under observation. The dye is injected into the blood stream to provide better contrast in the final diagnostic images. The dye is injected via an intravenous IV in the arm or hand.

Digital Subtraction Angiography

Digital Subtraction Angiography is a medical imaging test used to provide the doctor with visual data of the blood flow through the brain. The procedure involves inserting a catheter into an artery in the leg, and navigating it up into the brain. A dye is then inserted through the catheter, while the X-Ray scans are taken. This provides better contrast in the final diagnostic images, allowing the doctor to see the blood flow more clearly.
