Left Anterior Oblique or LAO Position
Просмотров 16 тыс.10 лет назад
The Left Anterior Oblique or LAO is obtained with the patients LEFT chest wall against the sensor or film cassette. This view is often used in angiography to better visualize the arch of the aorta, and its major branches to the head and upper extremities (arms). Easy to remember: LAO - "Lay Aorta Open" (so you can look into the arch).
Right Anterior Oblique or RAO Position -
Просмотров 45 тыс.10 лет назад
The Right Anterior Oblique Position or "RAO" is often used during an Upper Gastrointenstinal Flouroscopy study (UGI or "barium swallow") to better visualize the esophagus. In this position, the esophagus may be visualized without overlap from the cardiac shadow.
Autoregulation of Cerebral Blood
Просмотров 58 тыс.10 лет назад
The brain maintains relatively constant cerebral perfusion over a wide range of blood pressure, through a mechanism of local control called "autoregulation". The mechanism is through a sphincter-like vasoconstriction or dilatation of the pre-capillary arteriole feeding the capillary bed. This mechanism increases perfusion (rCBF) in response to falling pH and/or rising pCO2.

Multiple bilateral symmetric gray-matter lesions should always suggest a toxic or metabolic encephalopathy. Carbon monoxide (CO) intoxication may mimic the flu or drunkenness. CO selectively damages the medial lenticular nucleus of the basal ganglia of the brain. It may also affect the cerebellum and the hippocampus. Rapid diagnosis and treatment is successful for most patients. The most import...

Can a person fly with an arachnoid cyst?
Homogenius..
Code?Circuit ?
Omg … is this for real ? In 1998 age 39, I had a carotid dissection … now open .. I do CrossFit .. lots of sit-ups .. I guess I’m too old now … no longer fit the profile … male age 39-45 if I remember correctly .. This takes me back .. carotid dissection, diagnosed as a migraine, shot of immitrex .. immediately stroked out .. coma for 3 days, couldn’t speak or spell. Had to do a tour of Asia pacific , pt/INR tests in Singapore, Hong Kong and Australia … always remember the Singapore doctor surprised at 7.5mg of Coumadin “enough to kill a horse” … but here I am 25 years later.
I am a patient having diagnosis FOCAL DSYCOGNITIVE SEIZURE and as per my my MRI it's showing Developmental of venous anomaly left celleberal hemisphere. Inspite of having regular medicine I have 6-8 seizures episodes per month. What should I do? Is there any possibility for its surgery?
Has anyone else who has suffered from this? I was involved in a suicide attempt about 35 years ago and have had an atypical Parkinsonism for those years since the poisoning.
I am a colloid cyst patient myself with severe-Unilateral hydrocephalus. The cyst was 15 mm. The obstruction showed symptoms at the age of 3 and required immediate surgical treatment.
Hi I'm from the UK, I really enjoyed the video it was explained well 😊 I was wondering if you could help me?
Whats about pineal region mnengioma? 😊
Outstanding
Rip, Akira toriyama🙏
lovely
Lovely presentation. Thanks
Thank you 🙏🏻
Way to separate and big for christmas lights
I m suffering from sphenoid sinus with sinusitis, my brain reports are clear , is that dangerous?? But drs said I don’t any surgery , it will be cure from anitibiotics
did you recover? I also have sphenoid sinusitis
When do we see the diaphragm?
errrr that's not a normal find CT Thorax dude.....
This lecture I loved thanks ❤❤❤❤❤
Thank you soooooo much
Thank you
The best by far..
I remember you are neuroradiologist. Why are you posting a pulmonary CT scan?
Thank you
I have a 1.4cm cyst
I have bad headaches and they find that I have pineal syst but the pain is not from that because is very small I have no nausea or vomiting but pain is everyday
I have a sphenoid mass, but I’ve had two ct scans and they both say different things. One says mucocele and that was found on ct plus mri. The second one years later says sphenoid retention cyst. So now I am confused :(. I saw an ent and he said watch and wait but lately I’ve been having horrible ear pain, cheek pain and constant bloody noses all on the left side which is where it is. How do I get a doctor to take this serious? I’m so tired of the pain and it makes me not want to live. They just keep giving me antibiotics and I’ll be ok for a bit then the pain comes right back.
Hello. How are you now
hello can we have a update ?
Thank you!
What about toxo,tb,ncc??
i have got a venous malformation in the left cerebral hemisphere its 0.77mm and getting epileptic attacks from it. I went through egg,mri,ct scan and last thuesday went through a seldinger research through the legs to the brains using levetericatam 500mg 3x a day and lacosamide 50mg 4x those are surpressing the brains, but feel like a zombie all day and night long. Still waiting for a answers from my neorologists of 2 hospitals. If anyone had a idea of it please respond is it dangerious is it removable? thanks already greetings.
My cat’s breath smells like cat food.
Thankyou so much🌟 🌴
So great 😮
Very informative video . Can a colloid cyst cause symptoms without hydrocephalus? . I have a 6mm colloid cyst but no hydrocephalus, I have headaches and nausea.
Hi vrinder i have also cyst from where you are going to treated
I’m from Uk but have not found a doctor to treat it yet
I had a CT Sinus done & today, I follow up with my ENT for my results. I am so scared. I read that I have “mucosal thickening in the sphenoid sinuses.” How is that treated? I’m scared to have any type of surgery UNLESS I am awake 😩
What’s the update did it go away without you doing surgery
@@navie3644 Well I have Chronic Sinusitis. My ENT doesn’t think it’s bad enough to where I would have to have surgery. WHICH IS GREAT! But after him thoroughly reviewing my CT Scan results, he believes all or at least most of the inflammation is due to allergies. So, I’ve been referred to an allergist for allergy testing & we’ll just go from there. Really hoping that allergies is the culprit & I can work on treating that for relief 🙏🏽
I have one, then later was identified as an arachnoid cyst. I don't know why the identification changed. I don't have symptoms. My neurologist said if my vision changes abruptly or I start projectile vomiting, go to ER immediately
Can ct scan miss pancoast tumor
How does having a large (4cm) arachnoid brain cyst affect you?
Turns the light on but won’t turn off.
Great lecturer
Your lectures are usefull for me!
Gtreat lecture. Thanks sir!
Are they hard to distinguish? My doc still doesn't know dva, low grade tumor or ms possibility because of o band in fluiy
In 1991, I was diagnosed with a pineal dermoid cyst. My Neurosurgeon first inserted a VP Shunt. This stopped the blinding headaches, I was living with for years. He then performed a Craniotomy, which was unsuccessful. Now, almost 32 years later, I am still alive and the pineal tumour is still present. I can really count myself lucky to still be alive, after so many years, since it was discovered initially.
as a innate cyst, i has this collid cyst syptomps from early childhood aroun 10 years old. I developed tinitus in that age, always had sleeping problems, telling my parents " i have a fly in my brain, there is so much noise in my brain." I came to age of 30 with this colloid cyst even without knowing it. On 23th December 2019, i was hit by a car while crossing the roads which resulted in my skull fracture (epidural hematoma) After 8 months of my accident, i had brain MRI written that i had 7mm colloid cyst in the 3rd ventricle. My colloid cyst has become symptomatic after this accident. I am feeling that there is someting on my left side of brain ready to explode, so much pressure. I had unvolutary chin movements because of left side of pressure. When i put my head to pillow at nights, pressure increases.
Sending love to you and yours. ❤️

Thanks for NOT answering my question regarding having a large Maxillary Retention Cyst! With having major Cushing Symptoms!
You need to see a doctor not ask one on RUclips. Go to your GP!!
How are you doing and what are or where your symptoms?
I've got a degenerative neurological condition that finally put me to a wheelchair a few months ago plus a dozen other neurological conditions. All of them extremely painful. I'm 40. I must be the only person who believes that I'll ever get better. All neurologists gave up on me years ago. I'm just in a process of detoxification and changing my type of treatment so this lady connected me to this wonderful herbal doctor who put me on the right track with just his herbal supplement and natural diet Thank you ❤🌞 and all the best 🍀 am forever thankful #drobaedo 🍀🍀
I have an Retention Maxillary Sinus Cysts! And I’ve read this can cause Cushing Disease, in which I have many Cushing Symptoms! Can it?
