3 Tesla, Fully Digital MRI Scanner

Aster Medcity is among the first in India to have 3 Tesla MRI- a fully digital system for MRI scanning that provides exceptional image quality and detail to facilitate accurate diagnosis in neuro, cardiac, musculoskeletal and body imaging. The system, which considerably increases the MR angiographic potential, has unique functional MRI capabilities.


256 slice CT Scanner

This most advanced and fastest CT scanner that can cover large anatomic areas in split seconds, it supports advanced applications like CT Angiography, perfusion imaging, Cardiac Imaging and CT Coronary Angiography. The Department is also one of the first facilities in the country to have CT Fluoroscopy for accurate needle placement in CT guided procedures.


Digital Mammo Tomosynthesis

An advanced Digital Mammography system, it provides high-resolution 3D image results using X-rays for quick detection of even the tiniest calcified lesion that’s in the precancerous stage. The X-ray tubes move in an arc, capturing 11 images in 7 seconds and these images are assembled in the computer to create highly focused 3D image throughout the breast, facilitating easier diagnosis.



The Dexa, utilizing x-ray beams of two different energies, facilitates accurate measurement of bone density and strength with lowest dose of radiation possible, especially for preclinical detection of osteoporosis and preventing complications.


Digital X-ray

Renders high-resolution radiographs with superior time efficiency. As no repetition and digital enhancement are required, rapid transfer of images for immediate investigation by Physician is made possible through integration with PACS.


Nuclear medicine with PET CT & Gamma Camera

  • Time of Flight PET CT
  • Accurate and early lesion detection of functional abnormalities and low FDG doses using Time of Flight technology

Lowest Radiation Dose Cath Lab Facility

This Catheterisation Lab (Cath Lab), with the help of Allura Clarity system, reduces radiation doses by 70%, offering significant benefit to the patient as well as staff. Used for Interventional Cardiology and Neurology, the low radiation facilitates repeated investigation if necessary and is also safe for children.

Flat panel Bi-plane Hybrid Cath Lab

The Biplane Hybrid Cath Lab Unit, which works in a sterile operation theatre environment, combines the traditional diagnostic functions of a Cath lab with surgical functions of an operating room. Designed to undertake complex Neuro vascular and peripheral vascular procedures and Hybrid surgical/ endovascular procedures, the Cathlabs here are the first to have the option of ‘Clarity’, an ingenious system that reduces the radiation dose by upto 70%, which is of significant benefit to the patients. The functions of the unit include:

Biplane Cath Lab
Bi Plane Cath Labs are capable of capturing 3D images in real time, and come with added components like 3D road mapping and post processing to help neurovascular procedures. It can perform interventional procedures in lesser time with lesser usage of contrast, in comparison to single plane.

Digital Subtraction Angiography (DSA)
A type of Fluoroscopy technique used in interventional radiology to clearly visualise blood vessels in a bony or dense soft tissue environment, images are generated using contrast medium by subtracting a ‘pre-contrast image’. Very helpful in diagnosing Neurological problems, the advantage of DSA is that the interference of bony structures can be eliminated.

3D Rotational Angiography
3D rotational angiography provides an image of a particular vessel or chamber while the camera rotates around the patient in a predefined arc, enabling viewing of the structure from multiple angles with a single injection of contrast medium, thereby saving the contrast load and its side effects. A faster procedure compared to conventional Angiography, it is beneficial for patients for whom dye load needs to be restricted and those who require abnormal kidney function test.

CT Like images
With the soft tissue imaging feature that provides enables CT like images, the patient need not to be sent for a CT examination separately. This is a great advantage for neurovascular cases where the mobility of the patient is restricted and timelines are crucial. Interventionist can access CT-like imaging right on the angio system and inturn the soft tissue, bone and other brain structures before, during, or after an interventional procedure. 3D soft tissue imaging supports diagnosis, planning, interventions and treatment follow-up.

Hybrid Cath Lab
In a hybrid application, the Cath lab doubles as an operating room so that a patient undergoing a cardiac cath procedure can have a surgery if required. Enabling the Doctor to address the patient needs quickly, eliminating the need to schedule an additional surgical procedure. As the hybrid cath lab can turn to any angle as required by the interventionist, and can be placed in the corner of the OT when not in use.
