We use thyroid scans to determine whether or not a cat is in fact hyperthyroid before proceeding with I-131 treatment. Below are thyroid scan images from two different cats, one who was positive for feline hyperthyroidism, the other negative. Without looking at the second picture below, can you tell the difference between the positive and negative images? (Click on each to view full-size versions.)

Here is the answer:

It’s February. And February means that National Pet Dental Health Month is here! Prior to anesthetic cleanings, patients must go through a thorough exam that includes chest X-rays and blood work. This screening is not only good to make sure the pet is able to undergo anesthesia but it is also useful in early disease detection. Our radiologists are here for you and your patients during this process, so please keep us in mind for any chest X-rays and/or ultrasounds you may recommend as a result of abnormal blood work.

Real-Time Ultrasound is the Wave of the Future

There will soon be three options for veterinary ultrasound imaging: 1) refer the case out to a radiologist or cardiologist, 2) have the radiologist or cardiologist come to your clinic for the ultrasound, and 3) have a sonographer perform the study while a radiologist or cardiologist remotely reads the case via real-time technology.

“Wait, what is that third option?” you ask.

Real-time ultrasounds are streamed over the internet from a sonographer — who travels to the DVM’s hospital — to a specialist, who reviews the images from their location, using real-time streaming. (Note: Real-time ultrasound should not be confused with the failed model of still image ultrasound transmission that results in missed information.)

Benefits of this service are many.

Combining the hands and skills of sonographers with the extensive knowledge of radiologists and cardiologists, DVMs can offer their clients a quality service at a lower cost, since the specialist no longer needs to travel to their hospital. Furthermore, the DVM has access to a larger pool of specialists, and the specialists’ report turnaround time is significantly faster. In many cases a report is sent to the DVM even before the sonographer has left the building.

Critical care veterinarians will have the added bonus of speaking with someone over the phone while both parties are looking at images. This will also allow for the radiologist or cardiologist to answer questions or help out with image interpretation.

Real-time ultrasound is unique to our company and is a service that we have been performing for the San Diego Humane Society every week for the past two years, and later in 2012 will be available to local veterinary practices.

The ability to perform the ultrasound will be limited to critical care veterinarians and sonographers, but the hope is that it will be an option for DVMs in the future. Our ultimate goal is for real-time ultrasound to one day allow for specialists from all over the country to consult on cases in the general practitioner’s hospital as the exam is being done.

So, as we say goodbye to 2011, we can also say goodbye to the old way of still ultrasound transmission and make way for for a new wave… real-time ultrasound.

René Garcia, DVM
Staff Veterinarian/ Imaging Intern

Dr. René Garcia joined our practice earlier this year as our staff veterinarian and imaging intern, making him in charge of all of our I-131 therapy feline patients. He is the doctor veterinarians and owners discuss cases with, and he helps to oversee all of the the pretreatment imaging, treatment, and hospitalization. We are very happy to have such a talented young man join our practice for a one-year stay with us, and we thoroughly enjoy hearing about his professional and life experiences that he brings with him from all over the world.

Here is Dr. Garcia’s story…

Growing up in South Miami, across the street from the Everglades, wildlife conservation and reptiles were always a big part of my life. After a brief career as a firefighter and EMT, I decided that my desire to be a veterinarian and travel the world were too strong for me to continue a stationary, lifelong career with the fire department. My career goal to become a veterinarian led me on the journey of a lifetime, to one of the most respected veterinary schools in the world at Massey University, in Palmerston North, New Zealand. After seven years of living abroad, experiencing different cultures, making friends all over the world, all while focusing on becoming the best veterinarian I can be, I returned to America to start a mobile veterinary hospital that services Los Angeles and Ventura counties.

Q. What is your life outside of VICSD like?

A. My life revolves around my best friend and buddy, Mako, a 7-year-old MN New Zealand Huntaway that was taken directly from the rugged, chilly, steep sheep country of central New Zealand, to the soft, warm, and pillowtop confines of his Sunset Cliffs home.

Q. We love Mako! What else are you passionate about in life?

An avid traveler, I have visited an average of three different countries a year for the past seven years. International travel has gone from being a hobby to a lifestyle. The next planned vacation is… six nights in Iceland in early spring, 2012! Two of those nights will be spent dogsledding, led by the strong Greenlandic dog team, while enjoying the wild and untouched Icelandic countryside!

Q. Which imaging modality have you most enjoyed learning about?

A. The advances in advanced imaging modalities over the past few years have been a fascinating trend to follow. And while the technology and quality of these amazing imaging modalities has improved exponentially, so has their affordability to the consumer. We can now perform a full CT scan of the thorax to more accurately look for pulmonary metastasis, or scan the abdomen for surgical planning for just a little more than 3 view radiographs of the same structures would cost the client. And as time passes, I expect the trend to move from traditional imaging practices to more advanced imaging modalities, just as the human field has done over the past decade. With all these tools and diagnostic capabilities at our fingertips, this is an exciting time to be a veterinarian!

Q. Is there a unique case where CT was used that really stands out in your mind?

A. One case that stands out to me was an older MN Labrador, with a history of thoracolumbar pain, elevated ALT, ALP, and cholesterol, with alopecia and a distended abdomen. Abdominal radiographs were unremarkable other than a mild hepatomegaly. Abdominal ultrasound revealed a diffusley hyperechoic liver, and a large right adrenal mass was identified, but it was not certain whether this adrenal tumor was invading the surrounding vasculature. After a CT with contrast was performed, accurate intraluminal invasion of the phrenicoabdominal vein and caudal vena cava was detected accurately. Surprisingly, local invasion into the epaxial and hypaxial musculature was also identified, helping explain the dog’s back pain in the absence of intervertebral disk disease.

Imagine your practice trying to operate without your practice-management software or without your radiograph machine. My intent is not to cause a scare, but rather to make you aware and stress that computers are mechanical devices that will fail.

The question is: Can your business risk an outage that could potentially last days?

Something that I’ve learned the hard way is that it’s not a question of if a computer will go bad, rather it’s when it will go bad. It may be a surprise, but most personal and entry-level business computers are not built to be rock solid, from a reliability perspective, so please understand that at some point a machine will fail. A machine going down can significantly impact your business until it is replaced or fixed. Sometimes this could be as trivial as replacing a wireless router, or could be as severe as a corrupted hard drive.

A Little Insurance

Spending a few extra dollars could pay off if and when your machine does fail. I think it’s a good idea to have a maintenance agreement on your machine that will ensure a replacement part is shipped to you within 24-48 hours that will get you back online. If your maintenance agreement will soon lapse, it’s time to consider a new machine.

Let us consider your server that houses your practice management software. Sure, you take daily backups, but what if the hard drive on the server fails? Even though you have the backup, you have to completely rebuild your server, which takes a great deal of time. Having a maintenance agreement or a backup machine will help minimize downtime that negatively affects your business.

Also consider other options that provide you immediate access to data via the web. VICSD has offered clinics the ability to submit, store, and review images for years through the cloud-based VPACS and will soon be rolling out Vetology, which will allow clinics to do the same and more via the web. Utilizing a service like VPACS or Vetology reduces the reliance on your in-house machines to be able to serve up images and ensures you will always have access to images.

What Should You Do Next?

First, think about the impact of a potential computer outage. If this has the potential to be significant, then consider how you would mitigate that risk. Are you tech savvy or do you know of a local computer shop that could help minimize risk of outages? If so, I strongly suggest you do a review of your infrastructure or engage a local team to get some help. If you have been running your practice-management software on a 4-year-old machine that has never failed, then consider yourself very lucky. I recently read a statistic that states hard drives fail 15 times more than vendors originally estimate. While you may not know computers that well, there are quite a few reasonably priced vendors that just want to help you. Finally, also consider services that will allow you to focus on your practice rather than on IT, such as Vetology.

-Josh Yoo, Head of IT

About me: I spent my previous life as a techophile working for IBM but have since seen the light and am following in my father’s footsteps to become a veterinarian. Seeing this industry firsthand, I have realized how hard veterinarians work and what little time they have to explore technology options that could help improve their practice. That’s where I might be able to offer a hand until I get my DVM.
