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.

Sim Hoffman – Understanding CT Myelograms

When physicians need to detect injuries, lesions, or tumors on the spine, they have a radiologist like Sim Hoffman perform a myelogram. This is a type of radiological technique that is used to build up an image of the spinal cord. Due to the mineral content of the spine, it can be extremely tough to find any kind of issue or injury.

Sim Hoffman

The procedure begins with a spinal tap being performed on the lower region of the spine. Once this is completed, the radiologist injects a contrasting dye into the spine. At this point, you may be placed on a rotating table and strapped into place. The table is then rotated, so the patient is upside down for a few moments, before being returned to a normal position. This allows the contrast dye time to spread through the spine. From here, x-rays are taken of the affected area and a blood patch is used to seal the wound made to the spinal column.

This type of procedure may be completed in order to diagnose a variety of different disorders that are related to the spine. If you have numbness in your arms or legs your doctor may request a CT myelogram. It is also used to check for spinal stenosis or a narrowing of the spine. It is also used to determine if you have any tumors or infections along your spinal canal.

While myelograms aren’t used very often these days, it can be a great tool for radiologists like Sim Hoffman to build a three-dimensional, computer generated image of the spine. If you have been experiencing spinal pain, and diagnostic tests like a CT scan or MRI are inconclusive, you may have to undergo a myelogram procedure.

Sim Hoffman on the Future of Molecular Imaging

A leading radiology expert in the United States, Sim Hoffman is naturally fascinated by the potential of molecular imaging. In simple terms, the premise of the method is to one day be able to successfully identify local biological processes with the help of medical imaging. The body has an inflammation somewhere that the radiologist wants to see? The doctor wants to understand certain metabolic processes? The answer to these medical conundrums can be molecular imaging.

Sim Hoffman (13)

We Are Not Actually That Far

Molecular imaging is more than a concept. In fact, it is already used in some form, mainly in the oncology field. Pharmaceutical companies are basing some of their medical solutions on this technology. There are ongoing clinical trials that could change the process of imaging evaluation, as we know it.

Cardiovascular Molecular Imaging

What’s available in the field of oncology, is not much more than a mere concept when it comes to cardiovascular imaging. With that said, the metabolic imaging of the myocardium (heart muscle) is already available. It involves the injection of a contrast material that contains glucose into the arteries of the patient. Then the imaging technology shows the glucose uptake of the myocardium. Even some inflammatory processes can be detected that way, but the technology is simply not refined yet to really work as a wide-spread molecular imaging solution.

Fighting the good fight in the last several decades, Sim Hoffman fully understands the impact that a readily available, diverse molecular imaging technology could mean to the field of medicine, and to science in general.

Sim Hoffman – A CT or MRI can be Valuable after Specific Concussions

As an expert radiologist, Sim Hoffman follows the standard protocols. When it comes to concussions, the guidelines usually don’t require CT or MRI imaging, but in certain cases, they are in fact the recommended procedure.

Sim Hoffman

Not all Concussions Were Created Equal

Certain concussions are more problematic than others, in some cases not even producing major symptoms despite their serious nature. Regardless, their identification is only possible through a careful medical evaluation of the case, along with its unique circumstances. Taking a CT or MRI is recommended when some or a combination of the following symptoms occurs:

There are signs that could make the presence of a possible intracranial injury likely

  • Symptoms suddenly worsen
  • Lingering impairment, especially if the symptoms gradually worsen
  • Having difficulties while trying to speak or not remembering one’s language
  • Vision problems
  • Worsening coordination or lacking fine motor skills (the patient is not capable of touching their nose for example)
  • One of the eyelids start to close
  • The patient is having difficulties swallowing
  • The patient is having trouble staying awake or feels drowsy
  • The patient has seizures
  • Persistent symptoms (they should usually go away in a week, or maximum 10 days)

When there is a chance for an intracranial hemorrhage, CT is the way to go, whereas MRI’s are the better choice when the patient needs imaging one or two days after the incident. An experienced radiologist like Sim Hoffman will identify the warning signs early on.
