To review the discoveries underpinning the introduction of cerebral PET scanning and highlight its modern applications. Important discoveries in neurophysiology, brain metabolism, and radiotracer development in the post—World War II period provided the necessary infrastructure for the first cerebral PET scan. A complete review of the literature was undertaken to search for primary and secondary sources on the history of PET imaging. Written autobiographies were obtained through the Society for Neuroscience Web site at www. A reference book on the history of radiology, Naked to the Bone , was reviewed to corroborate facts and to locate references. The references listed in all the articles and books obtained were reviewed. The neurophysiologic sciences required to build cerebral PET imaging date back to The last 60 years have produced an evolution of technological advancements in brain metabolism and radiotracer development. These advancements facilitated the development of modern cerebral PET imaging.
An MRI scanner uses strong magnetic fields and radio waves to take detailed pictures.
Learn about our expanded patient care options for your health care needs. Magnetic resonance imaging MRI is a diagnostic procedure that uses a combination of a large magnet, radiofrequencies, and a computer to produce detailed images of organs and structures within the body. Some MRI machines look like narrow tunnels, while others are more spacious or wider. MRI scans can last from 30 minutes to two hours.

Researchers at Aalto University and Turku PET Centre have developed a new method for simultaneous imaging brain activity from two people, allowing them to study social interaction. In a recent study, the researchers scanned brain activity from 10 couples. Each couple spent 45 minutes inside the MRI scanner in physical contact with each other. The objective of the study was to examine how social contact activates the brain.
The results were published in the theme issue Social Interaction in Neuropsychiatry of the journal Frontiers in Psychiatry. People don’t just react to external stimuli, but adjust their actions moment-by-moment based on what they expect to happen next,” says Riitta Hari, emerita Professor at Aalto University. Ordinary magnetic resonance imaging is used to scan one person at a time.
In the device developed at Aalto University, the head coil used for regular brain scans was divided into two separate coils.
Cerebral blood vessels glow orange in this picture, generated by a 7-tesla magnetic resonance imaging scanner at The University of Queensland in Australia. On a cold morning in Minneapolis last December, a man walked into a research centre to venture where only pigs had gone before: into the strongest magnetic resonance imaging MRI machine built to scan the human body. First, he changed into a hospital gown, and researchers made sure he had no metal on his body: no piercings, rings, metal implants or pacemakers.

History of neuroimaging
A head MRI magnetic resonance imaging is an imaging test that uses powerful magnets and radio waves to create pictures of the brain and surrounding nerve tissues. You lie on a narrow table, which slides into a large tunnel-shaped scanner. Some MRI exams require a special dye, called contrast material. The dye is usually given during the test through a vein IV in your hand or forearm.

When you’re in the early stages of falling in love, you might hide it from friends and family. But you can’t hide it from neuroscientists. By charting brain activity with an fMRI functional magnetic resonance imaging machine, scientists can spot telltale regions of your brain glowing joyously when you look at a photograph of your beloved.
But new research suggests that neuroscientists can tell you much more than what you already know that you’re madly in love. Like fortune-tellers who read brains instead of palms, they have begun to figure out how to determine the fate of your relationship by studying your brain activity alone. Not all in-love brains look alike. Several years ago, Xiaomeng Xu, now a postdoctoral fellow at Brown University School of Medicine, and her colleagues performed fMRI scans on 18 Chinese men and women who reported being in the early stages of romantic love.
Though all the study participants showed clear signs of love — looking at the face of their beloved triggered a flurry of activity in the areas of their brains involved in reward and motivation — the researchers identified subtle differences between the individuals’ brain scans. When the team followed up with the study participants 18 months later to learn how their budding relationships had turned out, they found a surprisingly strong correlation between certain characteristics in the original brain scans and the participants’ relationship status a year and a half later.
The team detailed its results in the journal Human Brain Mapping in early Now, another two years have passed, and the researchers have contacted 12 of the original study participants.

Back to Your pregnancy and baby guide. The scan checks the physical development of your baby, although it cannot pick up every condition. The week scan is carried out in the same way as the week scan. It produces a 2-dimensional 2-D black and white image that gives only a side view of the baby. The NHS screening programme doesn’t use 3-D or colour images. The scan is a medical examination.

The second trimester scan is a routine ultrasound examination in many countries that is primarily used to assess fetal anatomy and detect the presence of any fetal anomalies. Alternate names for the study include second trimester anatomy scan, fetal anomaly scan or TIFFA targeted imaging for fetal anomalies. The following structures should be visualized at a routine second trimester morphology ultrasound.
The second trimester scan is a routine ultrasound examination in many countries that is primarily routinely obtained to calculate estimated fetal weight (EFW) and estimated date of delivery (EDD): fetal skull: integrity and shape; fetal brain.
Ultrasound uses sound waves to create an image picture. The sound waves can not be heard and the power of the sound waves used is very low. In pregnancy an ultrasound scan can be used to look at the developing baby, the uterus and the placenta. An ultrasound is safe for both mother and baby because it does not use ionising radiation it is different to an x-ray. No evidence has been found of ultrasound causing any harm to either the mother or developing baby.
Pregnancy is an exciting time for both parents, but there can be worries. Talk to your doctor or midwife if there are any concerns or questions about your pregnancy and for more information before you decide whether or not to have a test done. Pregnancy, Birth and Baby website Pregnancy, Birth and Baby is a national Australian Government service providing support and information for expecting parents and parents of children, from birth to 5 years of age.
There are many different medical uses for an ultrasound scan during pregnancy.

The common first step will be a dating scan between weeks as we like to check your baby before 10 weeks. Before 7 weeks it may be too early to acquire this information. To obtain the best images possible, this scan is routinely performed internally and perfectly safe to perform during early pregnancy. At 7 weeks gestation a pregnancy sac should be seen within the uterus.
Within this sac will be an embryo, heart motion and yolk sac should be visible. Approaching 8 weeks, early brain formation is identified with a black space in the head called the rhombencephalon. Sometimes it may be too early to gather all the information required to confirm the stage of your pregnancy. In this situation you may be required to return for a repeat ultrasound in days.
Your doctor will inform you of the most appropriate time frame to return for this scan if required. If you have completed an IVF cycle and have received a positive pregnancy result at day 16, an internal ultrasound will be performed approximately 5 weeks following your embryo transfer. This ultrasound will confirm the location of your pregnancy and the number, size and heart motion of the embryo s.
