New SPECT scans study brain function instead of the structure
By Dr. Anthony Policastro
I have had a number of parents come and ask me about SPECT scans. The acronym stands for Single Photon Emission Computed Tomography. It is a brain imaging study that uses radioactive tracers to study brain function. Most other scans like CT and MRI pay more attention to brain structure. SPECT scans are still relatively new. There are some things that have been studied enough to have these scans be useful in diagnosis. These include things like Alzheimer's disease, dementia, seizure disorders, stroke, traumatic brain injury and brain poisons such as carbon monoxide or substance abuse. Physicians may find the information from SPECT scans useful in these disorders. The information is then used with other tests to determine the location and degree of problems. Recently, there have been further studies suggesting that SPECT might be useful in other disorders in the future. Most of these studies are still experimental, which means we do not have enough of them done to be able to get all the information we need. Over the next few years we will have that information. At that point, SPECT scans will become much more useful for newer disorders such as ADHD, bipolar disorder, depression, anxiety, Obsessive Compulsive Disorder, learning disorders and autism. These disorders all have two things in common. The first is that making a diagnosis right now is difficult. We usually have to use a lot of information from the history to make the diagnosis. The second is that there is not a clear cut test that will make the diagnosis. Therefore, many people with these disorders are looking for a test that can make the diagnosis. Unfortunately, at the present time, we can do little more than say when a test looks normal or not. An abnormal test might mean different things. After we gather more information, then we will have more of an understanding of just which findings mean what. In the meantime, any information from such tests is still useful but not conclusive. There are some individuals with a clear cut diagnosis. For that reason, the SPECT scan provided little additional information. In patients with an unclear diagnosis, the SPECT scan may be helpful. Even then it has to be used with other available information. Since SPECT scans are relatively inexpensive to set up, they are easy to arrange. The people that do them outside of the research setting will often indicate that they are a lot more accurate than is really the case. There are a lot of stories of people with one diagnosis and a SPECT scan suggested the diagnosis was wrong. However, those are the exceptions rather than the rule. In most cases, the use of SPECT scan adds little to the clinical picture. That will all change in the future.
Sussex County EMS to purchase 11 new automatic CPR devices Thanks to a Sussex County Council decision on Tuesday, May 19, 11 cardio pulmonary resuscitation (CPR) assist devices will be purchased for all primary Paramedic Response Units in the county. The devices automatically perform CPR chest compressions on patients, enabling paramedics, EMTs and firefighters in moving ambulances to remain safely buckled in their seats and focused on other aspects of patient care. The purchase makes Sussex County EMS the first agency in Delaware to purchase and use such technology. "These devices will improve survival rates for our patients while improving the safety of our public safety workers," said Sussex County EMS Director Glenn Luedtke. "The CPR-assist devices perform mechanical chest compressions that take the place of manual CPR. American Heart Association research has demonstrated that patients who suffer cardiac arrests have shown better survival rates when these devices have been used in place of manual CPR." The American Heart Association also has shown through its research that most people cannot perform CPR effectively after one or two minutes, due mostly to fatigue. That often forces acute-care providers to routinely switch positions when performing manual CPR, which could result in decreased efficiency and lost time. The total cost of the project is approximately $167,000, with Sussex County funding a little more than $90,000. The balance will be made up with funds from the State of Delaware. The new devices could be in use later this summer.
