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.

Dr. Sim Hoffman-A Closer Look at Mammography

Dr. Sim Hoffman has practiced radiology his entire career and has obtained significant experience and expertise in such fields of radiology as ultrasound, general X-ray, nuclear medicine, MRI, C.T., and such special radiology procedures as Myelograms and Arthrograms.

Another area within Dr. Sim Hoffman’s area of expertise is mammography, an aspect of medical imaging which provides physicians the opportunity to identify changes in breast tissue, as well as to locate breast cancer in its earliest stages.

Two basic types of mammograms are currently offered in the medical community. The first, known as screening mammograms, are used most often to detect signs of breast cancer in those women who aren’t experiencing any current problems or symptoms of the disease and generally involve the use of X-rays of each breast taken from two different angles.

The second type of mammogram, known as the diagnostic mammogram, is utilized if the patient is experiencing symptoms, or if a change in breast tissue is shown during the screening mammogram.

Mammograms are generally performed by a machine that takes X-rays at lower doses of radiation than what is emitted during any other routine X-ray. As Dr. Sim Hoffman knows, this small amount of radiation is needed to get the best quality images during the mammogram, so as to provide the medical professional the best opportunity to identify or eliminate the presence of abnormalities.


Dr. Sim Hoffman-What to Know About Nuclear Medicine

Dr. Sim Hoffman is a practicing Diagnostic Radiologist based in Buena Park, California. The Medical Director of the Advanced Professional Imaging Medical Group, Dr. Hoffman oversees offices in Buena Park, Huntington Park, and San Bernardino.

Among the areas of Dr. Sim Hoffman’s expertise is Nuclear Medicine; the practice of utilizing small amounts of radioactive materials, generally called “radiotracers,” to better evaluate and diagnose certain medical conditions within the patient.

A branch of medical imaging, nuclear medicine serves as a noninvasive diagnostic tool; one which can help medical professionals not only diagnose and evaluate the severity of heart disease, many types of cancers, endocrine disorders and neurological disorders but which also often aids in the treatment process. Typically injected into the blood, swallowed or inhaled, radiotracers are able to travel to the desired area with relative ease and emit gamma-ray energy which, when detected by a specially designed camera and computer system, works to create images for the physician to examine.

Nuclear medicine’s primary advantage, As Dr. Sim Hoffman knows, is that it has the unique capability to provide a more comprehensive picture of regions of the body not possible through other imaging methods. It also offers physicians the opportunity to identify certain types of diseases in their earliest stages of development.
