Basic knowledge and literacy is going the way of the dodo. I have met adults that have never heard of ww2, time zones, jfk, the civil war, bosnia, etc. general knowledge is gone. America is over.

Dear fellow Redditors! Our company developed a new image processing technology called Digital Variance Angiography (DVA). DVA allows the visualization of motion on image sequences generated by penetrating radiations. It requires angiographic image series, which are created by X-ray or fluoroscopic imaging and by the administration of contrast media (e.g. ICM, CO2) during various medical procedures. DVA technology provides 2-3 times higher SNR values compared to traditionally used DSA images, this opens the door to CO2 angiography and x-ray dose reduction. I'd really appreciate your thoughts and feedback about this technology. Next week we will have a free live webinar with one of our radiologist KOL.

Abstract

BACKGROUND AND AIMS

Serum concentrations of glutamate (Glu), Glutamine (Gln) and Gln/Glu ratio have consistently been reported to be associated with metabolic disorders and diabetes. The aim of this study was to examine the relationship between these metabolites with the presence of coronary artery disease (CAD) and CAD severity in Chinese patients.

METHODS AND RESULTS

2970 Chinese patients undergoing coronary angiography (CAG) in Beijing Hospital were enrolled. Baseline demographics and medical history data was recorded by questionnaires. Serum Glu and Gln concentrations were analyzed by isotope dilution liquid chromatography-tandem mass spectrometry (LC-MS/MS). Statistical analysis showed that CAD patients had significantly higher levels of Glu and lower Gln/Glu ratios compared with non-CAD control group. Glu was significantly positively associated with body mass index (BMI), fasting blood glucose (FBG), triglycerides (TG), creatinine (Crea), and uric acid (UA), and negatively associated with high-density lipoprotein cholesterol (HDL-C), while inverse associations between Gln/Glu ratio and these risk factors were observed. Glu levels increased and Gln/Glu decreased with the increase of CAD severity as represented by either the number of stenosed vessels or the Gensini scores. Logistic regression analysis demonstrated that, after adjusting for smoking status, obesity or overweight, hypertension, dyslipidemia, diabetes, stroke and family history of premature CAD, high Glu level and low Gln/Glu ratio were positively associated with CAG defined CAD as well as CAD severity expressed by Gensini score.

CONCLUSIONS

We identified Glu and Gln/Glu ratio independently associated with CAG defined CAD as well as CAD severity in Chinese patients undergoing CAG.

As the title describes ... and if yes, what are the next steps?

Are there any treatments or surgeries if something is confirmed with these tests.

I have this feeling that all testing is good to rule out very bad cases, but in the end... does it change anything?

In the 9th edition of Kanski’s ophthalmology

It says “Fluorescein angiography (FA) is never needed these days. However, if undertaken it typically shows a round hyperfluorescent window defect with a hyperfluorescent centre”

Is this a typo as all the images I see have hypofluorescent centre or am I missing something

Eg: https://www.aao.org/image/cone-dystrophy-8

https://www.medhelp.org/posts/Urology/Painful-nocturnal-erections--AV-fistula-left-penile-artery--urgent-opinion/show/3053444

I’m very surprised I haven’t seen this before but it is fairly new (2020). Short summary:

• person has painful night time erections (as some do here and I have experienced as well) for years

• fluctuates between HARD flaccid and LONG flaccid. Has other symptoms as well

• angiogram shows fistula.

• other things are present as well with other tests but seem unrelated to symptoms

This isn’t a smoking gun but it lines up with u/Casperrb31’s arterial theory. The only downfall here is that the embolization could make him fully impotent because of the fistula location and the doctor isn’t 100% if they are connected.

Coronary angiography the test is used to find out if there is any blockage in the coronary artery, it is an imaging test that uses x-ray to view the blood vessels the X-rays provided by angiography are called as angiograms. This test is usually done to study narrow, blocked, malformed or enlarged arteries or the veins in the heart.

What happens in Coronary angiography:-

In coronary angiography the doctor will inject a liquid I through the thin flexible tube called as catheter, the doctor will treat the catheter into the desired hartree from the access point the access point is generally the arm but it can also be your groin. This dye make with blood flowing inside the blood vessel visible on the accessories and this is used to examine any narrowed or blocked area in the blood vessels, did I know that is inserted is later on eliminated from the body by kidneys and urine. This test is also known as cardiac angiogram,  catheter arteriography or cardiac catheterization.

Why it is done:-

Coronary angiography is basically recommended in conditions like-

• Symptoms of coronary artery disease
• Chest pain
• Congenital heart diseases
• Any blood vessel problems or chest injury
• New or increasing chest pain
• Pain In chest, neck, jaw, or arms
• Any heart valve problem

Risks:-

With most of the procedures done to the heart and the blood vessels there are some risk such as radiation exposure for the x-rays that are used here are some of the major complications and potential risk that include-

• Stroke
• Heart attack
• Kidney damage
• Infection
• Excessive bleeding
• Arrythmias
• Injury to the catheterized artery

What to expect:-

Before the procedure:- Before the angiography procedure start total health checkup will be done including past medical history allergies and the medications you take, some vital examinations like blood pressure and pulse is also checked.

During the procedure:- During the procedure and IV line is inserted into the vein of your arm, electrodes will be placed on the chest to monitor the process. Are small inches on is made at the entry side and a short plastic tube is inserted to the artery the catheter is inserted through the plastic tube into the blood vessels and a carefully threaded to the heart or the coronary artery.

Has anyone ever had an eye angiography? Anyone know anything about fluorescein? They had to inject intravenously for eye angiography.

I am very stupid and don't understand why 1.3 - 3.2 is = -1.9 instead of -2.1 someone please help my 0 IQ self, thanks.

Hello,

I have been given a task to subtract very large (positive) integers in C, I know somewhat what I'm supposed to do, that is, declare the integer as a string and then first convert each character in the string to an integer and somewhat loop it to subtract each integer from last character to front like normal mental subtraction we do in real life.

Does anyone know the code that I'm supposed to use, because I'm totally new to this and can't really figure out how I'm supposed to subtract each character(integer) from back to front of the string and finally output the answer back as a 15-digit character.
