Wake Radiology Oncology Services
Launches New Web Site
A new comprehensive web site for Wake Radiology Oncology Services was launched in
January at www.wakeoncology.com. Full explanation of the various procedures are
explained and case studies presented.
How Imaging Procedures Assist in the Alleviation of Back Pain:
Interventional radiology procedures available at
Wake Radiology help in minimizing back pain
In addition, the web site provides backgrounds on the radiation oncologists, and is
intended to expand as new functionality is added.
Web site designer and architect is Spence Hackney Design of Durham, NC.

annually resulting in an enormous number of lost
man-hours of work. The prevalence of these
conditions is at least 5% annually (1,2,3). Most cases are treated conservatively with rest, non-steroidal
anti-inflammatory drugs, or physical therapy. A small percentage of cases require surgery. Unfortunately,
since imaging abnormalities do not correlate with symptoms in most cases (4), a specific diagnosis
cannot be made, yet patients have continued pain.
Percutaneous injection techniques have been utilized for back pain management for many years, but
historically have been performed without imaging guidance (1). More recently, minimally invasive
imaging-guided percutaneous techniques utilizing primarily fluoroscopy and computed tomography
have been employed to confirm needle placement, thereby increasing precision. In most cases,
better results and reduced complication rates have made these procedures grow in popularity (1).
Cervical, thoracic, lumbosacral, and sacroiliac pain can be treated safely and effectively with local
injections of anesthetic and/or long-acting steroids into facet joints, sacroiliac joints, selective nerve roots,
spondylolytic regions, and the epidural space (1). The purpose of this article is to highlight one
approach to the epidural space through the sacral hiatus (Figure 1) using c-arm fluoroscopy.
With the patient in a prone position (to enhance comfort and virtually eliminate movement), c-arm
fluoroscopy is used to identify the sacral hiatus in the lateral projection. Using sterile technique and
local anesthesia, a 5-inch, 22-gauge spinal needle is directed into the sacral hiatus and advanced until its
tip reaches the level of S3. This level maximizes exposure of the sacral roots (Figure 2) to the injected
solution, yet is caudal enough to minimize the risk of dural puncture (Figure 3). An injection of < 5-ml.
of nonionic myelography-approved iodinated contrast confirms needle placement with an “upside-down
Christmas tree” configuration, but is typically unnecessary since the c-arm affords excellent visualization
of the needle in two planes. For patients with ipsilateral pain, the needle bevel is directed to the
symptomatic side (1). A solution of 5 ml. (40 mg./ml.) of Triamcinolone Acetonide Injectable
Suspension (Kenalog-40), 4-5 ml. (5 mg./ml.) of 0.5% Bupivicaine HCL Injection (Sensorcaine-MPF),
(continued on page 2)
(Epidural injection continued from page 1)
and 1 ml. of 1% Lidocaine HCL Injection (10mg./ml.) is injected to achieve
immediate pain relief and long-term anti-inflammatory therapy. Lidocaine
reduces any pain the patient may experience from the pressure of the
injection, however it can be eliminated.
From start to finish, the procedure takes less than 5 minutes in experienced
hands, especially if the patient is consented and prepared by the
technologist prior to the arrival of the radiologist. Generally, the patient
experiences immediate and often complete pain relief, which lasts
3-4 months on average.

welcomes Dr. Louis F.
Posillico to its staff.
Previously, Dr. Posillico
served as a staff
radiologist with Staff
Care in Irving, TX,
Precision Health Imaging
in Modesto, CA along
with a number of other
assignments.
Dr. Posillico earned his
MD from Georgetown
University and served
his internship and
radiology residency
at the University of
Pittsburgh Medical Center. He was a Nuclear Medicine
Fellow at Duke University Medical Center. He is currently certified
by the American Board of Radiology and the American Board
of Nuclear Medicine.

Wake Radiology Garner Office to
Move, Expand in Late Summer
Village Radiology in Chapel Hill
becomes Wake Radiology
Wake Radiology Diagnostic Imaging will expand its facilities and
move the Garner office to a new location in late summer 2004,
according to Bill Johnson, Wake Radiology Practice Administrator.
Village Radiology Consultants in Chapel Hill will soon undergo a
name change to Wake Radiology Diagnostic Imaging.
The new office will be located at the Health Park at Timber Drive,
adjacent to the new Rex Wellness Center. Physician offices in the
Garner area will be notified well in advance of the move in order
to facilitate an easy transition and to assist patients in finding the
new imaging facility.
The office will keep its same phone number, (919) 662-9500,
and fax number, (919) 662-2244.
Village Radiology Consultants, Inc. at 110 South Estes Drive in
Chapel Hill has been serving the local medical community since
1993 when Wake Radiology Diagnostic Imaging, Inc. in Raleigh
purchased the practice.
Wake Radiology Managing Partner Dr. Robert Schaaf explains,
"We believe one name will simplify the scheduling and reporting
process, a seamless approach across the entire practice."
The morning breakfasts at Wake Radiology North Hills, West
Raleigh, Cary and Chapel Hill offices have concluded with
the holiday fare served in December. The breakfasts,
initiated in celebration of the practice’s 50th anniversary,
greeted a variety of staff from practices nearby to the
four locations.
“Sharing our anniversary with so many new friends was
really satisfying to us all,” said Ceily Davis, Wake Radiology
Marketing Administrator.

“Wake Up With Wake Radiology”
Hibernates In Winter
We welcome William J. Vanarthos, MD as Scannings’ new Medical
Editor. Dr. Vanarthos joined Wake Radiology in 1999. He received
his medical degree from New York Medical College in Valhalla,
New York. He completed a combined internship and residency
in Diagnostic Radiology at Jackson Memorial Hospital as part of
the University of Miami School of Medicine Program in Miami,
Florida. Dr. Vanarthos further completed a Musculoskeletal
Radiology fellowship at North Carolina Baptist Hospital as part of
the Bowman Gray School of
Medicine program in WinstonSalem. Dr. Vanarthos is board
certified in diagnostic
radiology by the American
Board of Radiology. Prior to
