I think you must have grown out of your heart murmur...
Did your doctor mentioned anything about fluid overload or big heart in your files or records?
If it is not, then I presume that your racing heart beat should not be due to your cardiac past history...
Answers: Nothing said about fluid overload or big heart. -
wtf is this?

You probably have a condition called General Anxiety Disorder...Originally posted by ndmmxiaomayi:Topic closed, so post here.
Answers: Nothing said about fluid overload or big heart.
I shall let alfagal talk to you about this condition first and see if you agree you have the condition mentioned...
REFERRAL TO ALFAGAL
This patient presented with tension headache and palpitations associated with poor concentration, restlessness, profuse sweating, diarrhoea and poor sleep.
He has been self medicating with Panadol for his headache but to no response. He also has a history of cardiac murmur and bronchial asthma when he was young but has resolved now.
Sought follow-up with cardiologist up to 15 years of age. I ruled out the possibility of a cardiac and respiratory origin of his palpitations and am thinking of the possibility of General Anxiety Disorder. -
Alfagal, please answer in the other thread...

This thread is reserved for questions that we may not have the ability to answer... If this happens, you can post your questions here and the discussion will then be open to the public...
Example: Homeopathy, Acupuncture or Aromatherapy... there may be more... -

Here is one of the questions that I personally have no idea of as this is part of homeopathy practice, and this is posted by forumnite starblue
I shall leave this question to the floor...
i wanted to ask this: they say during menstration, gals shouldnt drink green tea or take pineapple and watermelon. true or not> and why ah??? -
Actually I have always heard from my mom that pineapple and tea will cause a heavier flow during menstruation, so if u dun wan to have a messy period, avoid these two at all costOriginally posted by renorenal:Here is one of the questions that I personally have no idea of as this is part of homeopathy practice, and this is posted by forumnite starblue
I shall leave this question to the floor...
but I googled up on pineapple and its relation to menstruation and this is what I found:
# Some herbal teas like raspberry leaf tea and cramp bark tea have been known to relieve menstrual cramps. Speak with a trained herbalist to learn more about how to properly take these teas.
# Stock up on pineapples. Fresh pineapple juice contains a lot of bromelain, an enzyme that is thought to help relax muscles and therefore help with menstrual cramps.

Today learning how MRI machines work. But don't understand. Who can help?

Thank you rainee. It is very useful.Originally posted by rainee: -
Read another website about MRI. It talks about T1 and T2, but I see no difference between them. Is there any difference between them?

I am really not that sure about this...Originally posted by ndmmxiaomayi:Read another website about MRI. It talks about T1 and T2, but I see no difference between them. Is there any difference between them?
Anyone care to explain? -
Clinically, I may know very little about it... but what I know goes like this... I may be wrong...Originally posted by ndmmxiaomayi:Today learning how MRI machines work. But don't understand. Who can help?
Our human body contains up to several thousands of water molecules, even in the organs, we do have a certain amount of fluids to keep our bodily functions stable.
The functions of MRI (magnetic resonance imaging) is self-explanatory through its name... When the body of a person is placed in the machine (the whole area is a magnetic field), it will release a resonance or a wave to resonate the water molecule (which have a slight magnetic charge polarity) around the main magnetic field which is static. This is then picked up by a receiver coil and translated into a data.
This, in conjunction with radio waves can be used to produce very detailed and high definition images (slices) of the brain.
Radio waves are of a relatively low frequency and are thus harmless. There is no evidence that exposure to magnetic fields are in any way harmful, provided that you do not have any magnetic materials on or inside your body such as a cardiac pacemaker.
I don't know any further about electromagnetics and the units of tesla they use, perhaps someone can come in and enlighten... -
actually u are referring to MRI or fMRI?Originally posted by ndmmxiaomayi:Read another website about MRI. It talks about T1 and T2, but I see no difference between them. Is there any difference between them?
recently studying on fMRI and doing a project on it now..
FMRI scans use the same basic principles of atomic physics as MRI scans, but MRI scans image anatomical structure whereas FMRI image metabolic function. Thus, the images generated by MRI scans are like three dimensional pictures of anatomic structure. The images generated by FMRI scans are images of metabolic activity within these anatomic structures.
T1:The amount of time it takes for for the atoms to return to their equilibrium value is called the "spin lattice relaxation time" or (T1). T1 is thus, a measure of the half-life of inverted spins. (in 2-D, imagine the magnetic force changing from a 90 deg direction to 0 deg)
T2:The amount of time it takes for for the atoms to return to their equilibrium magnetization value along XY axis (transverse axis) is called the "spin-spin relaxation time" or T2. T2 is, as a result, measures the rate of change of spin phases. (in 2-D, imagine the magnetic force changing from 0 deg to 90 deg) -

alright then, as stated abv, they use e same physics to do MRI n fMRI, definitions for T1 and T2 shld still stand. jus tat MRI is focused on anatomy, fMRI is more on funtions or metabolism of e whatever is being scaned.Originally posted by ndmmxiaomayi:My school says it is MRI. -

read bout something ineresting in my email:
STROKE IDENTIFICATION
During a BBQ a friend stumbled and took a little fall - she assured everyone that she was fine (they offered to call paramedics) and just tripped over a brick because of her new shoes. They got her cleaned up and got her a new plate of food - while she appeared a bit shaken up, Ingrid went about enjoying herself the rest of the evening. Ingrid's husband called later telling everyone that his wife had been taken to the hospital (at 6:00pm, Ingrid passed away.)
She had suffered a stroke at the BBQ - had they known how to identify the signs of a stroke perhaps Ingrid would be with us today. It only takes a minute to read this - Recognizing a Stroke ----- A neurologist says that if he can get to a stroke victim within 3 hours he can totally reverse the effects of a stroke... totally. He said the trick was getting a stroke recognized, diagnosed and getting to the patient within 3 hours which is tough.
RECOGNIZING A STROKE
Thank God for the sense to remember the "3" steps. Read and Learn. Sometimes symptoms of a stroke are difficult to identify.
Unfortunately, the lack of awareness spells disaster. The stroke victim may suffer brain damage when people nearby fail to recognize the symptoms of a stroke.
Now doctors say a bystander can recognize a stroke by asking three simple questions:
>
> 1. *Ask the individual to SMILE.
> 2. *Ask him or her to RAISE BOTH ARMS.
>
> 3. *Ask the person to SAY A SIMPLE SENTENCE
> (Coherently)
> (example: "It is sunny today")
If he or she has trouble with any of these tasks, call 9-1-1 immediately and describe the symptoms to the dispatcher. After discovering that a group of non-medical volunteers could identify facial weakness, arm weakness and speech problems, researchers urged the general public to learn the three questions. They presented their conclusions at the American Stroke Association's annual meeting last February. Widespread use of this test could result in prompt diagnosis and treatment of the stroke and prevent brain damage. -
...alfa... this forum is yours as well, you can start up a new thread if you want to talk about some topics you find interesting to stimulate questions

was thinking if paste too much stuff here machiam reading newpapers..who will wanna read a thread full of such stuff??Originally posted by renorenal:...alfa... this forum is yours as well, you can start up a new thread if you want to talk about some topics you find interesting to stimulate questions
so nvm lo wait till like this thread hits a certain number of pages then move on to the next one lo?
anyway, stroke: does it always happen to the same spot? (guess not..) if not, then how come they suggested with three of those tests only? wats e rational behind such tests?
