• Metallic artifact reduction.
• Reduction in radiation dosage

• 1.5T Light speed GE
• 1.5T Avanto Siemens
• 3.0T Achieva Phillips
• 3.0T Ingenia Phillips

MR imaging has ushered sea change in medical diagnosis due to its extensive clinical use. The latest acquisition of 3T ingenia from Phillips gives us high quality images. It has 70cm bore and has more space which reduces patient anxiety. The scans are faster.

In head there is advanced neuro imaging package, motion free brain imaging, SWI for traumatic brain injury and advanced diffusion sequences. ASL – non contrast brain perfusion imaging will now be possible. High quality functional MRI will be performed. Fat quantification in liver will be performed mDIXON technique. Healthy liver has about 5-6% fat content. Fatty liver is seen in those patients with excessive alcohol consumption, non alcoholic fatty liver disease (NAFLD). The patient NAFLD are at risk of developing cirrhosis and liver failure. Ultrasound has 70% sensitivity in detecting fat in liver (much less in obies patient). Liver biopsy while accurate is invasive with risk of complications. mDIXON provides high quality way of quantification fat in liver.

In cardiac imaging – myocardial viability studies and myocardial perfusion studies can be performed. Breast MRI – it is most sensitive test to detect early breast cancer in women at high risk. Those women having strong family history of breast cancer should undergo this examination. Dense breast is better evaluated by MRI. In breast implant MRI is method of choice. In pre operative staging MRI is the accurate way of determining size and extent of breast carcinoma. Evaluation of response of cancer to drug treatment is better evaluated by MRI. After surgery residual tumor can be assessed by MRI. Oncology imaging – whole body examination are possible due to rapid scans. DWIBS is used for reduction of metastases and lymphnode enlargement. MR neurography - allows clear visualization of peripheral nerves.

X-Ray has been an age old diagnostic procedure. The addition of an image intensifier (IITV) has revolutionised X-Ray radiology. In recent times, the images obtained by X-Ray machine have also been digitized. When X-Rays modality is utilised for real time diagnostic purposes like myelography, bronchography, barium studies, urethrogram, fistulogram, hysterosalpingography (HSG), sonogram, T-tube cholangiography, PTC., the use of IITV is extraordinary. The X-Ray exposure is significantly redued to the patient and also to the radiologist doing the procedure. At OKAY Diagnostic Research Center, IITV equipment (Siemens) was installed in the year 1987. Over all these years, the faculty has gathered enormous experience in conducting various procedures.

OKAY Diagnostic Research Center has installed a modern GE Logiq 500 equipment which is a high end machine for performing dynamic cardiac and vascular studies. “Power doppler” facility is also present in this machine which enables one to visualise smaller sized vesels especially useful in looking at renal and foetal cerebral vasculature. The person behind the machine is a fully trained cardiologist with vast experience in the field. Computer networking enables him to obtain views and opinions of fellow experts online. Image storing facility is helpful to the patients for evolution of their functional cardiac status. High frequency probe enables to do peripheral vascular doppler examination with precision in detecting obliterative plaque / thrombus.

As a key contribution to women health, OKAY Diagnostic Research Center provides a state-of-art dedicated GE Mammography system capable of identifying small soft tissue pathologies of breast. It provides high resolution with magnification and better contrast facility at short exposure time. The modern equipment exposes the patient to a lower X Ray radiation (0.25 Rads for 2 view bilateral mammography) than conventional X-Ray units which entail a radiation of about 3.2 Rads or more. The screening guidelines by the American Cancer Society emphasise mammography for all women between the ages of 40-49 years once in two years and once in a year for those above 50 years of age. Early diagnosis is the crux for the successful management of Breast cancers and doctors can do invaluable service to post-menopausal women by advising them mammography. In the eventuality of finding a pathological lesion, sonography of the breast is done free of cost to ensure a definitive diagnosis. Facility for a sono-guided biopsy is also available. A lady technician is always available for conducting this investigatin.

For Osteoporosis management, OKAY Diagnostic Research Centre ushers in Bone Densitometry Solutions form GE-USA. Osteoporosis is a silent, progressive disease characterized by decreased bone density and increased bone fragility. The disease may progress silently for decades with no symptoms unit fractures occur. Women are at the greatest risk. Bone loss in the major risk factor that can be modified in mid-life to reduce fracture risk. Bone loss can be reduced by treatment but it is difficult to restore the microarchitecture of the skeleton once bone has been lost. Early detection and intervention are crucial. Here comes the utility of Bone Densitometry which assists physicians in diagnosis, fracture risk assessment end monitoring response to therapy.

OKAY Diagnostic Research Center was amongst the first to acquire the high end sonography machines in Rajasthan.
