IDEAS Study (Alzheimer’s)

Princeton Radiology Participated in Largest Brain Amyloid Scan Research Study

Princeton Radiology is a registered PET imaging site for the Imaging Dementia – Evidence for Amyloid Scanning (IDEAS) study

sponsored by the Alzheimer’s Association and managed by the American College of Radiology (ACR) and American College of Radiology Imaging Network (ACRIN) from February 2016 to the study’s conclusion in December 2017. Princeton Radiology offered Medicare-covered amyloid PET scans to study eligible Medicare patients who were referred by participating IDEAS dementia specialists (neurologists, psychiatrists and geriatric medicine physicians). The research study sought to determine the clinical usefulness of PET imaging of brain amyloid deposits in the diagnosis of patients who are being evaluated for Alzheimer’s disease and dementia.

Diagnosing Alzheimer’s disease is complex. With no single test currently available, diagnosis is based on an individual’s history, physical examination and cognitive testing. Amyloid PET imaging represents a potential major advance in the assessment of people with cognitive impairment. The scan visualizes plaques present in the brain that are prime suspects in damaging and killing nerve cells in Alzheimer’s. Before amyloid PET, these plaques could only be detected by examining the brain at autopsy. The IDEAS study gathered data from Medicare beneficiaries to determine if amyloid PET scans help physicians to make more informed treatment decisions.

HEALTH MATTERS: Innovative Treatments Target Liver Cancer

Did you know that the incidence of primary liver cancer has more than tripled since 1980?

More than 40,000 Americans will be diagnosed with primary liver cancer this year, according to the American Cancer Society. And thousands of others will be diagnosed with secondary (metastatic) liver cancer, cancer that spreads to the liver after starting somewhere else in the body.

While surgery remains the gold standard for treating liver cancer, advances in medicine have made more treatment options available, especially for patients who may not be able to tolerate surgery or in cases where tumors are too large to be removed safely.

At the Edward & Marie Matthews Cancer Center at University Medical Center of Princeton, patients have access to a full range of services for the diagnosis and treatment of cancer, including liver cancer.

Liver Basics

Your liver is your largest internal organ and is positioned under your right ribs just beneath your right lung. It consists of two lobes, and weighs a total of about 3 pounds. It is also unique in that it has two blood supplies — the portal vein and the hepatic artery.

Your liver performs many vital functions including removing toxins from your blood, breaking down and storing nutrients that power your body and repair tissues, and producing bile to help your body absorb nutrients.

Many primary liver cancers are related to the hepatitis B or hepatitis C virus, which increase the risk for liver cancer. Other common risk factors include:

Gender. More men develop liver cancer than women.

Cirrhosis. A disease that causes scarring of the liver and is most associated with alcohol abuse and hepatitis, cirrhosis increases the risk for liver cancer.

Diabetes. Type 2 diabetes has been linked with an increased risk of liver cancer, usually in patients who have other risk factors such as heavy alcohol use, chronic viral hepatitis, or a combination of the two.

Obesity. Obesity can increase the risk for liver cancer as it is associated with diabetes as well as non-alcoholic fatty liver disease, which can lead to cirrhosis.

In addition, liver cancer can also be caused by other cancers that have started elsewhere in the body and metastasized to the liver. Metastatic liver cancer is most commonly associated with colon, lung and breast cancer.

Advances in Treatment

Traditional treatment for liver cancer typically involves surgery, chemotherapy and external beam radiation.

However, not all patients are candidates for surgery and some may not respond to traditional chemotherapy and radiation.

Today, there are several innovative approaches — such as radioembolization, chemoebolization and microwave ablation — that are making treatment more precise and more accessible to a broader number of patients.

With radioembolization, radiologists insert a catheter into the hepatic artery — the blood supply to the tumor — and insert tiny beads that lodge in the artery and give off small amounts of radiation, selectively targeting the tumor.

The procedure, which is performed through a small incision in the groin or the wrist and guided by X-ray images, kills the cancer cells and shrinks the tumor while sparing the surrounding healthy liver tissue.

Radioembolization is a generally a treatment option for cancer that is largely confined to the liver and for patients who meet certain baseline standards for liver function.

Similar to radioembolization, chemoembolization uses a catheter in the hepatic artery to delivery tiny beads of chemotherapy to the tumor. It is most beneficial in patients whose cancer is predominately limited to the liver.

Both radioembolization and chemoembolization block or reduce blood flow to the tumor, helping to kill off the cancer cells. Because the main blood supply to the liver is through the portal vein, healthy liver cells are relatively unharmed.

Another procedure, microwave ablation uses heat to destroy tumors. With microwave ablation, doctors — guided by an ultrasound or CT scan — insert a needle-like probe into the tumor. The probe emits heat from microwave energy that reaches temperatures greater than 100 degrees and kills the cancer cells.

Microwave ablation is typically used to treat smaller tumors, generally no more than 2 inches across.

All three procedures are generally well tolerated by patients. Side effects are typically mild and may include low-grade fever, abdominal pain and nausea. Usually, the procedures are performed on an outpatient basis.

In addition, because the procedures are precisely targeted there is normally little damage to healthy liver cells.

An Individualized Approach

As with most diseases, there is no single right approach for treating liver cancer. Each patient is different and requires a treatment plan that is specific and targeted to their unique condition.

Fortunately, innovations in cancer care are enabling doctors to manage complex cancer cases with more precise treatment, ultimately providing better outcomes for their patients.

If you have been diagnosed with liver cancer, talk with your doctor about your treatment options and the safest and most effective approach for your individual condition.

Updated DXA Policy for Medicare Patients

March 6, 2017

Medicare covers DXA Bone Densitometry for certain Medicare beneficiaries who fall into at least one of the following categories:

1.) A woman whose doctor has determined she’s estrogen-deficient and at a clinical risk for osteoporosis, based on her medical history and other findings.

2.) Patient with vertebral abnormalities as demonstrated by x-ray to be indicative of osteoporosis, osteopenia, or vertebral fracture.

3.) Patient receiving or expecting to receive glucocorticoid (steroid) therapy equivalent to an average of 5.0mg of prednisone, or greater per day for more than 3 months.

4.) Patient with primary hyperparathyroidism.

5.) Patient being monitored to assess their response to or efficacy of an FDA-approved osteoporosis drug therapy.

Medicare beneficiaries who meet the above criteria may have a Diagnostic DXA once every 24 months (more often if medically necessary).

In addition to the many ICD-10 codes for fracture, the following diagnosis codes, when used with a DXA Bone Scan (77080) will be accepted and paid by Medicare:

Z78.0 Asymptomatic menopausal state
Z79.3 Long term (current) use of hormonal contraceptives
Z79.51 Long term (current) use of inhaled steroids
Z79.52 Long term (current) use of systemic steroids
Z79.83 Long term (current) use of bisphosphonates
Z87.310 Personal history of (healed) osteoporosis fracture

Please note – Medicare will deny any claim that says “Screening DXA Bone Density” without any other indication and your patient will have to sign an ABN and pay out of pocket.  

If you have any questions, please do not hesitate to contact us at 609.921.8211.

Princeton Radiology Collaborates with Local Urologists to Offer The Next Generation in Prostate Care

Princeton Radiology has acquired UroNav software by Invivo. With this new software we are able to gather pre-biopsy MRI images of the prostate and then seamlessly transfer them to local Urologists. Using UroNav, these Urologists can fuse the pre-biopsy MRI images with real time ultrasound-guided biopsy images for excellent delineation of the prostate and suspicious lesions, as well as clear visualization of the biopsy needle – allowing Urologists to directly aim biopsy needed at lesions. Better images means better results.

Prostate cancer is the only type of solid organ tumor that is usually diagnosed sight unseen with hit-or-miss tissue biopsies.

For decades, Urologists have used a systematic, but blind approach to sample prostate tissue in men with an elevated PSA level and no palpable lesion, taking up to 18 core needle biopsies in scattered sections of the organ. Using this method doctors can’t be sure that they haven’t missed an aggressive tumor hidden in the 99% of tissue that was not biopsied, and they sometimes end up sticking needles into men who have no tumors, only an elevated PSA level.

Now, due to the precise targeting provided by MRI, many fewer biopsy samples are needed for accurate diagnosis – sometimes 80 to 90% fewer.  Fewer needle-sticks means lower risk of infection, bleeding, pain, and means and shorter recovery time. And thanks to the recent advance called multi-parametric MRI, specially trained radiologists can gauge the aggressiveness of a prostate lesion not only by how it looks, but also by how tightly its cells are packed, how blood flows through it, and its chemical makeup.

Targeted MRI/Ultrasound biopsy is poised to become the new standard in prostate cancer detection. Princeton Radiology is proud to collaborate with local Urologists to bring the next generation of prostate care to our patients.

Prostrate Care

Image: Magnetic resonance (MR)/ultrasound fusion combines MR images of the prostate (bottom left, red line) with real-time ultrasound images of the prostate (top left, red line) to assist in targeted biopsy of a previously identified lesion (green line). The location of the biopsy can be recorded (yellow line), and a reconstructed 3-dimensional map of the prostate can be generated at the conclusion of the biopsy (right). Standard biopsy cores and targeted biopsy cores are highlighted here for comparison.
