Prostate MRI

PROSTATE CANCER MANAGEMENT

Prostate cancer management has been challenging due to the absence of consistent and reliable imaging technique for diagnosis, localisation and characterization.

PROSTATE IMAGING IN PROSTATE CANCER

The enhanced soft tissue details from MRI provide valuable staging information for treatment planning. For low risk patients, MRI may track small change in low risk disease patients, allowing “active surveillance” for suitable patients.

WHY MACQUARIE MEDICAL IMAGING?

Macquarie Prostate Imaging Centre (MPIC) at Macquarie Medical Imaging (MMI) has developed an integrated multi-disciplinary approach, utilising multi-parametric MRI prostate in collaboration with urologists to improve the diagnosis and treatment of prostate cancer. MPIC worked with expert urology groups over the last two years, to refine and perfect MRI prostate imaging for the optimal treatment and assessment of prostate cancer.

MPIC currently perform in excess of 1000 prostate MRI studies annually utilizing:

  • Siemens and GE, wide bore 3-T MRI
  • Optimally refined scanning protocols
  • Dedicated trained MRI technologists
  • Dual reporting by radiologists subspecialised in prostate MRI
  • Comprehensive expert reports with relevant key images and diagrams developed in collaboration with urologists
  • Convenient location with on-site parking and free validation of parking fees
  • Weekday and Weekend appointments

MRI GUIDED BIOPSIES

Biopsies via trans-rectal ultrasound (TRUS) rely on random sampling, with variable accuracy and efficacy. MRI prostate improves prostate biopsy yield by guiding relevant regions of the prostate gland, for sampling via TRUS. MRI guided biopsies represent an exciting avenue for diagnosis of prostate cancer and differentiation of clinically significant or insignificant disease. Specialised MRI compatible biopsy system allows targeted biopsy, reducing sampling error and increases the quality and yield of tissue samples. Such expertise has been developed at MPIC.

WHAT DO WE PROVIDE FOR UROLOGISTS?

World-class service with:

  • Multi-parametric MRI images
  • Dual-reporting by subspecialised MRI Prostate radiologists
  • PIRADs reports with comprehensive and relevant key images and diagrams
  • K-TRANS analysis
  • Dedicated MRI slots during weekday, and weekend appointments for quick access and turnaround
  • Prostate biopsy service by trained urologists.

CT – High Resolution and Low Dose

Why CT?

Computed Tomography (CT) is a type of medical imaging that utilises cross-sectional x-rays and digitised computer imaging to created two and three-dimensional images of the body.

CT is regarded as the most widely used tool for the diagnosis and prognosis of a variety of complex diseases. As an imaging modality CT provides a significant amount of additional data, which other scans such as ultrasound and x-ray cannot provide.

However, there are concerns among medical practitioners over radiation exposure for patients. For this reason medical practitioners may choose to avoid CTs to perform less than optimal scans such as an ultrasound or x-ray.

High radiation exposure to children and young adults is a valid concern. The medical imaging equipment manufacturers are developing CTs with significantly lower radiation dosages in their latest, state-of-the-art equipment.

When should a CT be requested?

CT scans are the most beneficial type of imaging investigation to study certain parts of the body such as soft tissue, lungs, abdomen, pelvis, head and neck, as well as mapping of blood vessels.

Cancer Imaging and Surveillance

The National Cancer Imaging Centre (NCIC) at Macquarie Medical Imaging uses CT as one of our primary modalities for the detection, treatment and surveillance of cancers. CTs are particularly useful for diagnosing cancers in the lung, liver and abdomen. CT scanning can also be beneficial for planning areas in radiotherapy and biopsy as it can detect cancer.

CT is the most utilised method of surveillance for post-therapy patients. The low-dose option offered at MMI gives patient the best quality with the lowest rate of exposure available on the market.

Technology at MMI

GE, as a premier manufacturer of state-of-the-art medical imaging equipment, has produced the HD750. A CT machine with the lowest radiation sold to date with the highest resolution images, this machine consistently produces significantly low radiations dosages recommended by ANZSPR.

We have evaluated various CT machines by a variety of manufacturers against quality of images, resolution of images, radiation dosages and (operational) diagnostic capacity and we decided to install the HD750 as the best and lowest radiation dosage CT machine for the calibre of work produced at MMI.

How we do it

MMI adheres to the highest possible standards in imaging service and delivery. We have:

  • worked exclusively with the GE HD750 to produce the highest quality images with the lowest doses of radiation available.
  • specially trained radiographers who repeatedly implement peer- agreed consistent imaging protocols.
  • subspecialised reporting or internal second opinion reporting for complex studies to ensure that the diagnosis is performed to the highest standard.
  • efficient post-reporting services tailored to our referrers.
  • immediate appointments available.

SPINAL INTERVENTION & BACK PAIN MANAGEMENT

Radiologists at Macquarie Medical Imaging (MMI) have a particular interest in the treatment of neck (cervical) and back (thoracic and lumbar) pain. Pain at the base of the spine (sacrum and coccyx) is a common complaint and can also be treated.

Back pain is a very common problem, and one that mostly resolves with rest and simple analgesia. If back pain persists it can be investigated with simple radiological investigations such as x-ray and CT scans at Macquarie Medical Imaging (MMI). These modalities can demonstrate osteoarthritis and intervertebral disc disease but they are also useful for the exclusion of sinister pathology such as tumours.

Macquarie Medical Imaging offers a number of interventional spinal and back pain management injections. Interventional spinal techniques are minimally invasive. The staff at MMI are able to assist patients by providing imaging with CT, MRI, and co-registered SPECT-CT bone scan to help diagnose the cause of the back pain and, if clinically indicated, provide the spinal injections.

What are the benefits of a SPECT-CT Scan at MMI?

SPECT-CT is where a nuclear medicine study is performed together with a CT scan and the images or pictures from each are fused or merged together. The fused scan can provide more precise information about how different parts of the body function and can help identify problems more clearly.

SPECT-CT at MMI provides the ability to merge or combine the images often allowing the nuclear medicine specialist to more accurately pinpoint the site of any abnormality on your nuclear medicine scan. This may be of particular importance in certain clinical situations, when the interpretation of an area of interest may change depending on its location. For example, in small areas like the spine, it is sometimes hard to determine from the nuclear medicine imaging alone whether the abnormality lies in the bone or the adjacent joints – fusing a SPECT with CT provides added confidence in identifying where the abnormality is.

Common interventional spine procedures Macquarie Medical Imaging specialists utilize, include:

  • Facet joint injections
  • Epidural injections
  • Selective nerve root block / Perineural injections
  • Sacroiliac joint injections
  • Cervical spine injections
