O-Arm® Surgical Imaging System

The O-arm® Surgical Imaging System, now in use at Hartford Hospital, is a multi-dimensional surgical imaging platform that is optimized for use in spine, orthopaedic, and trauma-related surgeries. It provides real-time, intra-operative imaging of a patient's anatomy with high quality images and a large field-of-view in both two and three dimensions.

By integrating O-arm surgical imaging technology with Medtronic's StealthStation® surgical navigation systems, surgeons are able to perform less invasive procedures and confirm the precision of advanced surgical procedures before the patient leaves the OR.

The O-arm® Surgical Imaging with StealthStation® Navigation provides:

  • Speed in the OR: fast access to real-time, multi-plane 3D images (and 2D images)
  • Ease in the OR: full support of the unique workflow of spinal procedures
  • Safety in the OR: minimized radiation dose for surgical staff
  • Confidence in the OR: visualization to confirm hardware therapy placement, potentially eliminating revision surgeries

Sentinelle Breast MRI Coil

Doctors at Hartford hospital have a new tool in place to help them detect and diagnose breast disease with confidence, making the experience more comfortable for nervous patients who may learn they have breast cancer.

The new tool is called the Sentinelle breast MRI coil. It is an advanced Breast MRI diagnostic system that produces impressive, high quality breast MRI images. Better images mean a better, sometimes earlier diagnosis. Many factors affect image quality, including the ability of the patient to stay as still as possible.

The new system’s advanced ergonomic design is more comfortable, using positioning “wings” and sternum rest. A more comfortable patient moves less, and reduced motion provides better image quality.

“This advanced technology will not only offer better patient care, it will significantly improve the patient’s experience during the MRI procedure”, said Jinnah Phillips, M.D., Breast Imaging Radiologist at Hartford Hospital and Jefferson Radiology. “The coil’s unique design assures our patients are comfortable during the procedure, while providing much greater access to the breast for proper positioning and biopsy into regions of the breast that were difficult to access in the past. The ability to adjust the positioning of each coil to the patient provides superior image quality, providing greater confidence in diagnosis.”

It can be nerve-wracking to learn you need a biopsy. Hartford Hospital’s Imaging Center experts believe having more comfortable and efficient equipment can make the whole experience a better one.

The American Cancer Society (ACS) recommends MRI examinations in addition to annual mammograms for women with an especially high risk of breast cancer. Screenings are recommended for women with one of the following: a BRCA1 or BRCA2 gene mutation; a first-degree relative (parent, sibling or child) with the above gene mutation; exposure to chest-area radiation between the ages of 10 and 30; or a lifetime risk of breast cancer scored at 20%-25% or greater based on one of the several accepted risk assessment tools.

“Hartford Hospital is committed to providing the best in breast cancer detection and patient management,” said Jinnah Phillips, M.D. “The Sentinelle breast coil is a powerful new tool for our physicians and patients”.



Reinvestment and Recovery Act Grant Helps Fund New Facility

Hartford Hospital, a recognized leader in the treatment of stroke and vascular diseases, announces the installation a new, innovative imaging system that gives doctors the tools they need to more effectively diagnose and treat patients. Stroke is the number one cause of death for people over the age of 65. Early diagnosis and intervention saves lives and often, a patient’s livelihood: the longer a patient goes without treatment, the more likely that patient is to suffer irreversible damage.

The new neuroradiology suites at Hartford Hospital are equipped with the Artis zee® biplane system, a state of the art imaging system that gives doctors the best tools available to more effectively diagnose and treat patients. Bi-plane imaging equipment allows specialized physicians to obtain three-dimensional views of the patient’s anatomy from any direction, painting a clearer picture so physicians can better determine the next, best course of action for patients.

The system features two advanced x-ray detectors – called flat-panel detectors – that provide high-resolution images without the distortion common with conventional x-ray techniques. The detectors also help physicians visualize exactly where they should place interventional devices, such as guide wires and catheters, in precise detail and from almost any angle.

Hartford Hospital has a nationally recognized commitment to stroke treatment and neuro-interventional radiology has been a key component in the care of these patients. Hartford Hospital is ranked as one of the nation’s top 10 busiest stroke treatment centers by the Center for Medicare and Medicaid Services. There is no other stroke treatment center between New York City and Greater Boston that can provide these critical services to patients experiencing stroke.

Hartford Hospital received $325,000 from the American Recovery and Reinvestment Act of 2009 to help fund this important addition.

Stroke Warning Signs:

  • Sudden Numbness or weakness of the face, arm, or leg, especially on one side of the body.
  • Sudden confusion, trouble speaking or understanding.
  • Sudden trouble seeing in one or both eyes.
  • Sudden trouble walking, dizziness, loss of balance or coordination.
  • Sudden severe headache with no known cause.
Call 911 if you see or have any of these symptoms. Every minute counts.


A 'Slice' of Life

When someone arrives in the emergency department with a suspected heart attack, the rush begins. Patients are wheeled from the ED to the angiography suite to nuclear cardiology and the cardiac catheterization lab. Now an innovative imaging system so fast that it can capture images of an organ in seconds—and a beating heart and coronary arteries in only five seconds—is giving Hartford Hospital physicians a diagnostic edge.
 
The first in the state, Hartford Hospital’s LightSpeed VCTXTe scanner is many times faster than conventional multi-slice CT (“CAT”) scanners. In a single rotation lasting about a third of a second, the VCT captures 64 “slices” of anatomical data. The VCT (the “V” stands for volume) represents a significant technological leap in coverage area, image clarity and speed, creating spectacular three-dimensional views of organs, arteries and veins.
 
“The VCTXTe can be used for many clinical scenarios, including cardiac disease, stroke, chest pain and trauma,” says interventional radiologist Barry Stein, M.D., of Jefferson X-Ray Group, co-director of cardiovascular MRI and CT at Hartford Hospital. “The machine spins so fast that it ‘freezes’ the motion of the heart, providing clear images of the coronary arteries quickly and safely, potentially negating the need for an invasive angiogram to evaluate for coronary artery disease.”
 
The outpatient study requires only intravenous administration of contrast dye. The patient lies on a table as a rotating X-ray machine sends data to a computer display. With the new scanner, teams of specialists can view the images to plan procedures like stenting, balloon angioplasty or surgery.
 
Only a fraction of the five million Americans who arrive at the emergency department with chest pain are actually having a heart attack . “With a single VCT scan, clinicians can exclude the three most life-threatening critical conditions that cause acute chest pain—a tear in the aorta (dissection), a blood clot in the lung (pulmonary embolus) and coronary artery disease,” Dr Stein adds.
 
The VCTXTe’s negative predictive value of 97–98 percent means physicians can be very confident that no atherosclerotic coronary artery disease exists if a scan is normal. As part of the examination, a calcium score can also be acquired. A more powerful predictor of atherosclerosis than cholesterol levels, an elevated calcium score can help identify patients at risk for coronary artery disease.
 
“Until now, a CT scan was not fast or powerful enough to capture an image of a beating heart,” says Charles Primiano, M.D., an interventional cardiologist and co-director of cardiac CT at Hartford Hospital. “Now someone who may have a coronary blockage can have a noninvasive procedure instead of cardiac catheterization or angiography. They’re only in the scanner for a few minutes.”
