During a pregnancy the head circumference, abdominal circumference, Fumur and Amniotic Fluid index are monitored and measured at scans to check they are growing within the normal range e.g 10th, 50th and 90th centiles. Anything outside of the 10th and 90th range is considered not to be 'normal' and could be a sign of a problem. If the head circumference is measured and found out of this range e.g below the normal range then it could be a sign of FAS, Microcephaly or another type of mental disorder. However, any measurements within this range is considered to be normal.
The question is difficult to answer because it depends on what "small" actually means, like I say, if it is below the 10th centile range then it is too small and there COULD be a problem but if it has been measured to be within the normal range then the baby could just have a petite head with no mental issues.

Advantages of using indexes in database?
Advantages of an index over no indexIf no index exists on a table, a table scan must be performed for each table referenced in a database query. The larger the table, the longer a table scan takes because a table scan requires each table row to be accessed sequentially. Although a table scan might be more efficient for a complex query that requires most of the rows in a table, for a query that returns only some table rows an index scan can access table rows more efficiently.The optimizer chooses an index scan if the index columns are referenced in the SELECT statement and if the optimizer estimates that an index scan will be faster than a table scan. Index files generally are smaller and require less time to read than an entire table, particularly as tables grow larger. In addition, the entire index may not need to be scanned. The predicates that are applied to the index reduce the number of rows to be read from the data pages.7 If an ordering requirement on the output can be 7 matched with an index column, then scanning the index in column order will 7 allow the rows to be retrieved in the correct order without a sort.Each index entry contains a search-key value and a pointer to the row containing that value. If you specify the ALLOW REVERSE SCANS parameter in the CREATE INDEX statement, the values can be searched in both ascending and descending order. It is therefore possible to bracket the search, given the right predicate. An index can also be used to obtain rows in an ordered sequence, eliminating the need for the database manager to sort the rows after they are read from the table.In addition to the search-key value and row pointer, an index can contain include columns, which are non-indexed columns in the indexed row. Such columns might make it possible for the optimizer to get required information only from the index, without accessing the table itself.Note:The existence of an index on the table being queried does not guarantee an ordered result set. Only an ORDER BY clause ensures the order of a result set.
What technique can public health researchers employ to scan large amounts of data for trends?
Public health researchers can employ data mining techniques to scan large datasets for trends. This involves using algorithms and statistical methods to identify patterns, correlations, and anomalies within the data. Machine learning models can also enhance trend detection by automating the process and improving predictive accuracy. Additionally, visualization tools can help researchers interpret and communicate these trends effectively.

How is indexing faster than sorting when accessing data from a table?
Indexing can be faster than sorting. It can also be slower. It depends on how many rows your predicate clause is selecting, and on the data dispersion represented by those index keys. If you are selecting a few rows, such as less than 4% of the table, then by all means use an index. If you are selecting a lot of rows, such as more than 25% of the table, then the use of the index will usually degrade performance, so go for the full table scan followed by a sort. (Of course, now you are adding the use of sort space, so that is a consideration.) The break-even point depends on the particular RDBMS and on the structure of the data. If your RDBMS supports EXPLAIN PLAN, then use it, and learn to know what it means. Also, make sure you understand your data, because (sometimes) only you know the best way to query it, and it might make sense to override the optimzer and force a certain execution plan based on your knowledge.
If you have small head compared your body but your wife's head is the correct size as per her body then will the baby have correct head size or small?
There is no telling. Genetics cannot be predicted. You may be able to get this information during the ultrasound scan.
What is the difference between a ct head scan and a ct sinus scan?
A head scan looks primarily at the brain and a sinus scan looks only at the sinuses in the face region.
What does low density mean in a CT scan?
I had a low density undetermed spot by my lower right ear shown on a ct scan of the sinus. What are they looking for to do a MRI of the head.
Which medical scan is for visualizing soft tissue?
Mri of the body... Or a cat scan of the head
Ct scanning protocols for head trauma?
A brain scan after a head trauma is nearly always done without contrast, because bleeding also shows up white on the scan. The scan should be done as quickly as possible with the shortest scan time because patients with head injuries are often restless. If there is a suspected neck injury, the patients head will have be scanned in the position it is in, and the patient can not be moved into the 'head box'. After the scan, both brain and bone setting views should be looked at to establish if there are any fractures.
Can you scan your head on a computer scanner?
my friend just did it but the top of her head couldn't be seen! ;)
Small opaque densities surround the urethra. What does that mean on a CT Scan?
This could be areas of hardening or calcification around the urethra, the tube that you pee out of.
Is a catscan for the head?
A CAT scan can be used for the entire body.
