Dr. Sim Hoffman: Types of Interventional Procedures

Dr. Sim Hoffman has enjoyed a lengthy and successful career in the field of diagnostic radiology. A practicing Diagnostic Radiologist for more than 30 years. Dr. Hoffman has direct experience with many common and special radiological procedures in use today, including ultrasound, general X-ray, CT, MRI, nuclear medicine, arthrograms, and myelograms.

An experienced radiologist, Dr. Sim Hoffman is also well-versed in interventional radiology; a subspecialty often involving the expert use of small instruments to avoid the need for more costly exploratory surgeries, as well as to diagnose and sometimes even treating disease more effectively.

The following types of procedures are considered interventional:


This procedure is used to open up narrowed or blocked blood vessels through the use of a small balloon, which is inflated within the vessel itself.


This is a diagnostic procedure designed to gather images of blood vessels in such areas of the body as the kidneys, brain, heart and so on.

Endovenous Laser Treatment

An outpatient procedure, Endovenous Laser Treatment, or EVLT, involves the use of a very thin catheter inserted into the vein, which then emits a laser energy that targets and seals the vein closed.

Dr. Sim Hoffman currently operates and oversees three diagnostic radiology offices in Southern California.


Dr. Sim Hoffman-The Function of the Myelogram

Dr. Sim Hoffman oversees the operation of three diagnostic radiology offices in the southern California region. A Diagnostic Radiologist with more than 30 years of practice experience, Dr. Hoffman now manages Advanced Professional Imaging Medical Group offices in Buena Park, Huntington, and San Bernardino.

Trained at the LAC/USC Medical Center, Dr. Sim Hoffman is well-versed in such imaging procedures as mammography, general X-ray, nuclear medicine, ultrasound, CT, and MRI. He is also experienced in such special diagnostic procedures as arthrograms and myelograms.

Myelograms, as Dr. Hoffman knows, has a very specific purpose: to provide a better picture of potential issues with and between the bones of the spine. The Myelogram technique combines the use of X-rays with contrast material (a special dye), which helps the radiologist capture better images of the space and tissue within the spinal column. A myelogram is often performed to locate the presence of an infection, tumor, a herniated disc or arthritis in the patient’s spine.

This procedure involves the injection of dye into the subarachnoid space (fluid-filled space between the bones) so that the physician can see the spinal cord and nerve roots more clearly. Myelograms, as Dr. Sim Hoffman knows, are commonly followed by a CT scan so as to collect as much information as possible before the dye is gone.

Dr. Sim Hoffman-The Applications of Ultrasound Imaging

Dr. Sim Hoffman has been responsible for the oversight and leadership of Advanced Professional Imaging Medical Group, now with offices in Buena Park, San Bernardino and Huntington Park, California, for more than 30 years. A seasoned radiologist and expert in numerous medical imaging techniques, Dr. Sim Hoffman has direct experience with such procedures as general X-ray, nuclear medicine, MRO, CT, and mammography, as well as such special radiological procedures as arthrograms and myelograms.

Another technique in which Dr. Sim Hoffman is well-versed is ultrasound imaging, a relatively convenient, fast and affordable technology which has widespread application in medical diagnostics and evaluation. One of the more notable benefits of ultrasound imaging is that, in some cases at least, the pain or swelling patient is experiencing can often be quickly located and sourced using ultrasound findings. In addition, ultrasound imaging is a dynamic procedure, which can be useful when seeking to show a number of ongoing issues (such as the demonstration of an inguinal hernia).

Ultrasound, as Dr. Sim Hoffman knows, can be a useful tool for examining common issues or abnormalities within the abdomen, the vascular system, scrotum, the musculoskeletal system and more. Prenatal ultrasounds, however, are often performed not by radiologists, but by specialized obstetricians.

Dr. Sim Hoffman-Knowing More About Arthrograms

Dr. Sim Hoffman is an experienced radiologist with a broad medical imaging skillset. The Medical Director of the Buena Park-based Advanced Professional Imaging Medical Group since 1986, Dr. Hoffman has years of direct experience and expertise administering a variety of imaging techniques, including ultrasound imaging, nuclear medicine imaging, general X-ray, CT scans, MRIs, and mammography.

Dr. Sim Hoffman is also well-versed in so-called “special” radiology procedures, most notably Arthrograms. Arthrograms are techniques most commonly used to identify issues with the soft tissues within the structure of a joint.

Employing a special X-ray, known as a fluoroscopy, an arthrogram provides the radiologist the opportunity to highlight those tissues not visible using normal X-ray imaging. Such tissues as ligaments, tendons, cartilage, and muscles are best identified using an arthrogram, allowing the physician to better evaluate and diagnose problems affecting movement and causing pain within the joint. While a regular X-ray shows only the bone of a given joint, an arthroscopy can provide a more complete picture of the tissues within.

Arthrograms involve injections of contrast material, such as air, water, dye or a combination thereof, into the patient’s joint so as to ensure they show up during the X-ray imaging process. They are commonly recommended or used for further examination of the patient’s knee, hip, shoulder, ankle, wrist, elbow, and jaw areas.
