2 Case Reports of Gastric Ultrasound
Ethanol (CH3CH2OH), or beverage alcohol, is a two-carbon alcohol
that is rapidly distributed in the body and brain. Ethanol alters many
neurochemical systems and has rewarding and addictive properties. It
is the oldest recreational drug and likely contributes to more morbidity,
mortality, and public health costs than all illicit drugs combined. The
5th edition of the Diagnostic and Statistical Manual of Mental Disorders
(DSM-5) integrates alcohol abuse and alcohol dependence into a single
disorder called alcohol use disorder (AUD), with mild, moderate,
and severe subclassifications (American Psychiatric Association, 2013).
In the DSM-5, all types of substance abuse and dependence have been
combined into a single substance use disorder (SUD) on a continuum
from mild to severe. A diagnosis of AUD requires that at least two of
the 11 DSM-5 behaviors be present within a 12-month period (mild
AUD: 2–3 criteria; moderate AUD: 4–5 criteria; severe AUD: 6–11 criteria).
The four main behavioral effects of AUD are impaired control over
drinking, negative social consequences, risky use, and altered physiological
effects (tolerance, withdrawal). This chapter presents an overview
of the prevalence and harmful consequences of AUD in the U.S.,
the systemic nature of the disease, neurocircuitry and stages of AUD,
comorbidities, fetal alcohol spectrum disorders, genetic risk factors, and
pharmacotherapies for AUD.
These lecture slides, by Dr Sidra Arshad, offer a quick overview of physiological basis of a normal electrocardiogram.

SPECT Scan
1. > 1
Overview
A Single Photon Emission Computed Tomography
(SPECT) scan is a type of nuclear imaging test that
shows how blood flows to tissues and organs.
How does a SPECT scan work?
A SPECT scan integrates two technologies to view
your body: computed tomography (CT) and a
radioactive material (tracer). The tracer is what
allows doctors to see how blood flows to tissues and
organs.
Before the SPECT scan, you are injected with a
chemical that is radiolabled, meaning it emits
gamma rays that can be detected by the scanner.
The computer collects the information emitted by
the gamma rays and translates them into two-
dimensional cross-sections. These cross-sections
can be added back together to form a 3D image of
your brain.
The radioisotopes typically used in SPECT to label
tracers are iodine-123, technetium-99m, xenon-
133, thallium-201, and fluorine-18. These
radioactive forms of natural elements will pass
safely through your body and be detected by the
scanner. Various drugs and other chemicals can be
labeled with these isotopes.
The type of tracer used depends on what your
doctor wants to measure. For example, if your
doctor is looking at a tumor, he or she might use
radiolabled glucose (FDG) and watch how it is
metabolized by the tumor.
The test differs from a PET scan in that the tracer
stays in your blood stream rather than being
absorbed by surrounding tissues, thereby limiting
the images to areas where blood flows. SPECT
scans are cheaper and more readily available than
higher resolution PET scans.
What does a SPECT scan show?
A SPECT scan is primarily used to view how blood
flows through arteries and veins in the brain. Tests
have shown that it might be more sensitive to brain
injury than either MRI or CT scanning because it
can detect reduced blood flow to injured sites.
SPECT scanning is also useful for presurgical
evaluation of medically uncontrolled seizures (Fig.
1). The test can be performed between seizures
(interictal) or during a seizure (ictal) to determine
blood flow to areas where the seizures originate.
This type of scanning is also useful in diagnosing
stress fractures in the spine (spondylolysis), blood
deprived (ischemic) areas of brain following a
stroke, and tumors.
Who performs the test?
A specially trained nuclear medicine technologist
will perform the test in the Nuclear Medicine de-
partment of the hospital, or at an outpatient
imaging center.
How should I prepare for the test?
Wear comfortable clothing and be prepared to stay
for 1 to 2 hours.

complex partial seizures. The temporal lobe on the left
side of the brain shows less blood flow than the right,

the brain causing seizures.
