In keeping with our tradition of introducing high quality medical imaging services Doon MRI & Diagnostics is proud to introduce Digital Mammography system Senographe Care by GE Healthcare, USA.

Its soft gentle design complete with arm-rests, chest padding and arm-pit padding provides the highest level of comfort for the patient during the scan.

The machine automatically controls the degree of compression applied to the breasts for optimizing the amount of radiation exposure.

It automatically releases the compression once the scan is done.

High resolution imaging with enhanced sensitivity for cancer detection is ensured.  




MR defecography is technique to study disorders of ano-rectal function. It is indicated in patients having constipation, rectal incontinence, painful defection and rectal prolapse.. It permits analysis of the ano-rectal angle, opening of the anal canal, function of the puborectalis muscle and descent of pelvic floor during defecation. It provides good demonstration of the rectal wall, intussusception, enteroceles and rectoceles with excellent demonstration of the perirectal soft tissue. It allows assessment of spastic pelvic floor syndrome and descending perineum syndrome. No radiation hazard is associated with this procedure as was there in fluoroscopic x ray defecography. Images are obtained with patient at rest, at maximal sphincter contraction, during straining and during defection.

Functional MRI (fMRI) measures signal changes in the brain that are due to changing neural activity and is also referred to as BOLD imaging (Blood oxygen level dependent).

A person's brain is scanned while he or she is performing a certain physical task such as squeezing a ball or looking at a particular type of picture. When the neural activity is increased, there is increase in oxygen demand and the vascular system actually overcompensates for this, increasing the amount of oxygenated hemoglobin relative to deoxygenated hemoglobin.

Such techniques are being used in pre-surgical planning and in basic neuroscience research in areas such as memory, expressive and receptive speech, visual spatial processing and other cognitive processes



  • Quantitative measurement of tissue stiffness 

  1. Shear Wave speed (m/s)
  2. Young’s Modulus (kPa)

  • 2D color coded visualization of tissue stiffness

  • Image guidance with B-mode ultrasound images, allows for :-

      1.  Instant visual quality assessment of spatial stiffness, useful for detection and characterization of focal lesions

      2.  Better diagnostic interpretation with overlaying of shear wave stiffness images on the B-mode images 


      3.  Optimal placement of Regions of Interest (ROI) for quantitative stiffness measures

      4.  Sampling within the ROI provides tissue stiffness measures at any location in the ROI, unlike conventional fibroscan which  

            measures only the average stiffness within a ROI in a blind manner

  • Assessment and comparison of the degree of fibrosis in the same site of the liver on follow up imaging using this technique, which was not possible earlier

Doon MRI & Diagnostics has installed the State's first true Digital X-ray system from Carestream Health which is a mark of the global quality that we strive to provide. This is integrated with an advanced high frequency 800 mA X-ray equipment with IITV from Allengers Medical Systems.

DR Systems provide unparalleled image quality and drastically lower the radiation exposure to the patient.

They also improve the workflow of a radiology department by digitizing the entire process of taking an X-Ray.

All routine plain X-rays and special procedures including barium studies, intravenous urography (IVU), hysterosalpingography (HSG), retrograde cystourethrography (RGU) and micturating cystourethrography (MCU), etc. are performed using the DR system. 

Estimation of iron deposits in different organs of thalassaemia patients is an important aspect of their medical management . Serum ferritin has been used as a surrogate marker, but it is not specific because its level can be raised in inflammations such as hepatitis, infections and in liver damage . Although biopsy is the most reliable method for estimating organ iron overload, its invasive nature makes its implementation very limited.

The T2* magnetic resonance imaging (MRI) technique is a non-invasive, valid and reproducible method for assessing tissue iron loading, and therefore has important implications for clinical management of iron overload and the tailoring of chelation regimes. This method has allowed for early diagnosis of liver and heart haemosiderosis and a reduction in morbidity and mortality in thalassaemia patients

Doon MRI & Diagnostics is equipped with the most advanced 3D/4D Ultrasound and Color Doppler system Voluson E-8 Expert from GE Healthcare, USA having a break-through pure wave single crystal technology delivering high quality images.

It provides excellent 3D/4D study in pregnancy as well as fetal doppler study. 

Shear Wave Elastography on the LOGIQ S8 XD Clear ultrasound is the latest and advantageous technique for non-invasive quantification of liver tissue stiffness.

MR angiography is used to generate pictures of the arteries to detect any abnormal narrowing/dilatation or abnormal arterio-venous connections. MR angiography is often used to evaluate the arteries of the neck and brain, the thoracic and renal arteries and the arteries of legs. Magnetic Resonance Venography (MRV) is a similar procedure used to image veins.

​          From x-rays to Functional Imaging 




Although X-Ray Mammography remains the primary imaging modality in the evaluation of breast disease, the mammogram can at times be inconclusive for the presence or location of an abnormality. MR imaging has been used as an adjunct to mammography, particularly for patients with equivocal mammographic findings. The main advantage of breast MR imaging is its high sensitivity, with reported sensitivities for cancer ranging from 91% to 100% with varying specificity. Multiple investigators have shown that MR mammography may be useful to verify multifocality and multicentricity of breast cancer, differentiate scars from recurrences after breast-conserving therapy, screen high-risk groups who have a family history of breast cancer, investigate breast implants, examine breasts in cases of histologically proven breast cancer, metastasis with unknown primary

Diffusion weighted images are very commonly used in the assessment of acute stroke and are also widely used in oncology.

Diffusion Tensor Imaging , also known as MR Tractography non-invasively maps white matter tracts. Diffusion parallel to nerve fibers has been shown to be greater than diffusion in the perpendicular direction. This provides a powerful tool to study in vivo fiber connectivity in the brain in a noninvasive manner and preoperative planning of resectability of brain tumors. Application of this technique to stroke, Alzheimer's disease and pediatric brain development are being investigated.

​MR spectroscopy is a noninvasive method providing metabolic information about the brain. MR spectroscopy enables tissue characterization on a biochemical level surpassing that of conventional MR imaging. MR spectroscopy is also able to detect abnormalities that are invisible to conventional MRI because metabolic abnormalities often precede structural changes.


Non-invasive CT Angiography is a technique that shows the blood vessels of the body in great detail, without any discomfort to the patient. The scan hardly takes a few minutes to perform but the information it provides is very precious. It can show the functioning of the heart, the blood vessels of the legs, thigh, arms, abdomen, lungs etc in great detail.

Precautions to be taken before a non-invasive CT angiography:-

  • We need the patients kidneys to be working fine. For this we need the patients Kidney Function Tests to be done. We need the patients Blood Urea Nitrogen and Serum Creatinine reports
  • The patient would need to be fasting for 4 hours prior to the test.

In cardiac CT all scans are gated to the ECG trace. This allows us to position our data acquisition accurately in specific phases.

Using this modality we can perform the following procedures as part of a cardiac CT examination.

  • Calcium scoring
  • Coronary artery imaging
  • Functional assessment

Calcium scoring is a technique where the extent of calcification in the coronary arteries is measured and scored. There is a direct correlation between the extent of calcium in the coronary arteries and the risk of a future cardiac event. For example, a calcium score of more than 400 is considered severe and it would be necessary to take steps to prevent further advancement of atherosclerosis and plaque formation. The higher the calcium score, more likely is there a chance of severe stenosis as well. A calcium score of 0 does not rule out soft plaques, but statistically rules out significant coronary artery disease. Though the calcium score does not show soft plaques (which however are best seen on a CT angiogram), the higher the calcium score, the more is it likely that there are soft plaques as well. Rupture of a soft plaque is the commonest cause of an acute coronary syndrome (i.e. a heart attack). Calcium scoring is offered as a separate stand-alone test, but this is routinely performed as an initial part of the entire cardiac CT examination.

Indications of CT coronary angiography

  • Asymptomatic patients with family history of coronary artery disease
