Would a pulmonary function test accurately diagnose asthma?

Would a pulmonary function test accurately diagnose asthma?

Nearly essential: Asthma is not one illness, but several processes that appear in greater or lesser degrees in any one affected individual. Together they can lead to the functional problems we recognize as asthma. Pulmonary function tests measure air flow and volumes; accurately performed PFT's are indispensable in the diagnosis and management of asthma and COPD. ...Read more

Docs, could a transesophageal echocardiogram detect pulmonary hypertension?

Docs, could a transesophageal echocardiogram detect pulmonary hypertension?

Sure: any echo can look for indirect evidence of Pulm HTN such as right heart failure or high velocity tricuspid regurgitation. direct pressure measurements are not possible non-invasively and require a right heart cath. ...Read more

Echocardiography report, left ventricle, prominent septal bulge 1.2cm without tract obstruction, also resting wall motion abnormalities were present, spectral doppler shows impaired lv diastolic filli?

Echocardiography report, left ventricle, prominent septal bulge 1.2cm without tract obstruction, also resting wall motion abnormalities were present, spectral doppler shows impaired lv diastolic filli?

Complicated : To understand a report one needs to talk with one's physician. Resting wall motion abnormalities means areas of the heart are damaged and not contracting or squeezing normally. That is the heart "walls" are not moving correctly. Sometimes this can cause the wall inside the heart that separates the right and left side to "bulge". Impaired filling means the heart does not "relax" normally. ...Read more

The colour doppler echocardiography final diagnosis report: septal thickening, diastolic dysfunction. What does this mean?

Report: The wall between the right and left ventricles is called the septum. This was thicker than normal. The relaxation function of the muscle is not normal, this is the diastolic dysfunction mentioned. ...Read more

Vq scan and pulmonary embolism? How accurate is the scan?

Vq scan and pulmonary embolism?  How accurate is the scan?

Not realy very: Ventilation/perfusion scan (v/q scan or lung scintigraphy), which shows that some areas of the lung are being ventilated but not perfused with blood (due to obstruction by a clot). This type of examination is used less often because of the more widespread availability of ct technology, however, it may be useful in people who have an allergy to iodinated contrast or in pregnancy. Thanks. ...Read more

Spirometry results essentially normal spirometry. Hyperinflation questionable the single breath diffusing capacity is moderately impaired. COPD?

Possible: A reduced DLCO/Va points to damage or scarring in the lung tissue and emphysema (especially if you have been a smoker) or other interstitial lung diseases may be the cause. The normal lung function however is not compatible with COPD but then I don't understand what you meant by hyperinflation in the presence of normal lung function test. See a pulmonologist. ...Read more

Does echocardiogram reliably diagnose rv hypotrophy?

Yes: You probably mean hyper trophy which means thickened right ventricle. Either way, echocardiography is reliable. ...Read more

What are the differences between pulmonary perfusion scan and pulmonary ventilation scan?

What are the differences between pulmonary perfusion scan and pulmonary ventilation scan?

Lung V-Q scan: Ventilation scanning involves the patient breathing in a radiotracer while perfusion scanning involves injecting the radiotracer through an iv. The procedure is done usually to evaluate the presence of absence of a pulmonary embolism (usually a blood clot) and involves comparing the radiotracer's presence in the alveoli vs. Its presence in the lung circulation. ...Read more

When measuring ascending aorta size(horiz)from sinotobular junction to innominate artery is cardiac mri/mra for morphology more accurate test than cta?

When measuring ascending aorta size(horiz)from sinotobular junction to innominate artery is cardiac mri/mra for morphology more accurate test than cta?

Depends: Done properly, ideally with ECG gating, an aortic MRA is equivalent to an aortic CTA. The opinion from some vascular docs is an overestimation on MRA. This was probably from movement artifact and older scanners. The benefit of MRA is the lack of iodinated contrast and lack of radiation. It is in routine use at many large medical facilities to periodically track aortic enlargement- kids/adults ...Read more

Normal peak flow meter test, normal CT of lung, normal chest xray , normal echo, normal pulse ox / blood pressure can this rule out interstitial lung d?

Normal peak flow meter test, normal CT of lung, normal chest xray , normal echo, normal pulse ox / blood pressure can this rule out interstitial lung d?

Most likely: The results suggest that you dont have significant cardiopulmonary illness. However if your symptoms persist your doctor should consider other causes including non physical. ...Read more

Echo cardiograph report! 10 points!?

Echocardiography: What is the question? Echo is noninvasive ultrasound study of the heart. It tells us about the heart valves, chamber sizes, any clots, vegetations, tumors, septal thickening, wall motion, function of the ventricles( heart failure). Also special studies can detect septal defects. ...Read more

Could an echocardiogram detect pulmonary disease/pulmonary hypertension?

Could an echocardiogram detect pulmonary disease/pulmonary hypertension?

ECHO for PH: Pulmonary hypertension (ph) is often first detected by echocardiogram (echo) which estimates the pulmonary artery systolic pressure. The diagnosis is confirmed by right heart catheterization which measures mean pulmonary artery pressure and resistance. ...Read more

What's difference between High HD Contrast CT scan vs Normal Chest CT with contrast evaluating interstitial lung markings?

Different chest CTs: High resolution chest CT usually with out intravenous contrast is used to define interstitial lung disease pattern, whether diffuse or localized process. CT of chest examination with contrast intravenously usually looking for tumors or metastases and acute infection in the lungs. ...Read more

What is a plethysmograph used for?

Plethysmograph: Definition: A plethysmograph is an instrument for measuring changes in volume within an organ or whole body (usually resulting from fluctuations in the amount of blood or air it contains). When used in Lungs it measures lung capacity, when used in lower extremities can meausure circulatory capacity, in genitals changes in blood flow in penis, etc. ...Read more

Can computed tomography angiography show heart problems right?

Can computed tomography angiography show heart problems right?

It depends: On regular contrast-enhanced ct exams, cardiac abnormalities including masses or thrombus can be detected, but little information regarding the coronary arteries can be obtained. On a dedicated coronary ct exam with contrast (ekg gated), the coronary arteries can be evaluated for narrowing or blockages. This is usually not possible on regular ct exams due to motion. ...Read more

What is t2 hyperintense r/lower pole renal lesion demonstrates hyperintensity on non fatsaturated t1 image.Post contrast vascular phenomenon MRI Scan?

Appearance descripti: These words (presumably from a radiology report) describe what the MRI looks like (hyperintensity - very bright) & the location (lower part of the [renal] kidney) & the way the images were obtained (T2 weighting & fat-saturation T1 & dye [contrast]). All this means nothing without symptoms. For a doctor to help you, he/she needs to know what the MRI was trying to diagnose. W/o symptoms, means noth ...Read more
