Guidelines for Diagnostic Imaging During Pregnancy and Lactation

Watterson, Michelle G. In Wilhelm Roentgen, a physicist, demonstrated the first radiograph and opened a new window to medical diagnosis. His revolutionary discovery set the stage for even more amazing advances in the imaging of human disease. He emphasized the diversity among the scientists and medical specialists who contributed. Walter Dandy, a neurosurgeon, first performed ventriculography and pneumoencephalagraphy PEG in and Moniz, a neurologist, accomplished the first cerebral arteriogram in Oldendorf himself developed the basis for computerized tomography CT in and the technique was applied to clinical diagnosis by an electrical engineer, Hounsfield, in Finally, magnetic resonance imaging MRI was introduced.

Nuchal translucency is the name for the normal fluid space behind the neck of a foetus unborn baby that can be seen on ultrasound scans. A nuchal translucency scan also called first trimester of pregnancy screening is carried out during weeks 11—13 of a pregnancy. The scan uses ultrasound to screen for Down syndrome, or other chromosomal or inherited conditions in the foetus. Other non-chromosomal conditions, such as neural tube defects, abdominal wall defects, limb abnormalities and some congenital heart disease, can also be detected at this stage of the pregnancy.

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.

Half of the participants are still in the relationships they had just begun at the time of the brain scans three and a half years ago; the other six aren’t. Among the admittedly small sample, there is a striking divide between the original brain activity of the people whose relationships lasted and those whose relationships fell apart. Two key aspects of the participants’ brain activity correlated with their relationship longevity, Brown said.

The world’s strongest MRI machines are pushing human imaging to new limits

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.

Why would my doctor refer me to have this scan? · to confirm the exact date of the pregnancy and the due date; · to confirm the number of foetuses.

See wait times for diagnostic imaging See other wait times we track. While both types of scans take pictures of the inside of your body, they use different technology. Your doctor will choose what scan is right for you based on your symptoms and medical history. Learn how understanding the wait process helps you. Your doctor would like you to have a diagnostic scan to help them determine the right course of treatment. Your doctor determines which image MRI or CT is appropriate for you and sends a request to a hospital or imaging centre.

You wait for the hospital to contact you with your appointment time.

The history of cerebral PET scanning

On July 3, , the first magnetic resonance imaging MRI exam on a live human patient was performed. MRI, which identifies atoms by how they behave in a magnetic field, has become an extremely useful non-invasive method for imagining internal bodily structures and diagnosing disease. The life-saving medical technique has its foundations in the work of physicist I. Rabi, who during the s developed a method of measuring magnetic properties of atomic nuclei.

Date: April 28, ; Source: Aalto University; Summary: Researchers can now scan two people together, showing that touching synchronizes couple’s brains.

Read terms. Wharton, MD. This document reflects emerging clinical and scientific advances as of the date issued and is subject to change. The information should not be construed as dictating an exclusive course of treatment or procedure to be followed. However, confusion about the safety of these modalities for pregnant and lactating women and their infants often results in unnecessary avoidance of useful diagnostic tests or the unnecessary interruption of breastfeeding. Ultrasonography and magnetic resonance imaging are not associated with risk and are the imaging techniques of choice for the pregnant patient, but they should be used prudently and only when use is expected to answer a relevant clinical question or otherwise provide medical benefit to the patient.

With few exceptions, radiation exposure through radiography, computed tomography scan, or nuclear medicine imaging techniques is at a dose much lower than the exposure associated with fetal harm. If these techniques are necessary in addition to ultrasonography or magnetic resonance imaging or are more readily available for the diagnosis in question, they should not be withheld from a pregnant patient.

Breastfeeding should not be interrupted after gadolinium administration. With few exceptions, radiation exposure through radiography, computed tomography CT scan, or nuclear medicine imaging techniques is at a dose much lower than the exposure associated with fetal harm. If these techniques are necessary in addition to ultrasonography or MRI or are more readily available for the diagnosis in question, they should not be withheld from a pregnant patient.

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.

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.

This process involved draining the cerebrospinal fluid from around the brain and replacing it with air, altering the relative density of the brain and its surroundings, to cause it to show up better on an x-ray , and it was considered to be incredibly unsafe for patients Beaumont 8. A form of magnetic resonance imaging MRI and computed tomography CT were developed in the s and s. The desire to understand the human mind has been one of the main desires of philosophers throughout the ages.

Questions about thoughts, desires, etcetera have drawn psychologists , computer scientists , philosophers , sociologists and the like together into the new discipline of cognitive science. Non-invasive imaging of the human brain has proven invaluable in this context. The very first chapter of the history of neuroimaging traces back to the Italian neuroscientist Angelo Mosso who invented the ‘human circulation balance’, which could non-invasively measure the redistribution of blood during emotional and intellectual activity.

However, Mosso’s manuscripts have remained largely unknown for more than a century, and therefore it was the structural radiographic techniques to dominate the field of the imaging of the human brain.
