One of The first imaged X-ray

This image is very famous and it is sometimes found on radiological books,
It is one of the earliest X ray taken by German scientist called Roentgen on December-22-1895 ,
It was for his wife's hand and signet ring.
I don't know why he tried his experiment on his wife,
Although this image was taken more than 120 years ago
but the quality is not bad.

he named the invisible radiations as X-rays (or unknown rays)
Roentgen got the Nobel Prize in-1901

Hyperpolarized gas imaging

I found while googling this interesting new uses of the MRI:

•Until recently, MRI images of the lung had been very difficult to obtain due to the low hydrogen content of the lung.
•Hyperpolarized gas imaging requires that the patient inhale a laser-polarized noble or inert gas (xenon or helium). The polarized gas makes it possible for MRI to image the lung.
• This technique has already been successful at imaging the lungs of patients with emphysema and has clearly identified the regions of low ventilation that occur due to the disease .

patient problem with MRI

I found this image with the paragraph below in"Getting started in Clinical Radiology" imaging book and was really interesting ,
This patient is well prepared for his examination.He
brought a pair of pliers along to take his jewelry off .It took
him about half an hour.

I can't imagine how would be the resulting image after MRI scan or 
if that metal is highly magnetic and movable during the scan.

So before any MRI scan the Radiologist must get any history 
from the patient about any procedures the has been done before 
or previous accidents or truma because there may by any metallic particle  
that can move during the scan ( read the previous post) especially if foriegn body in eye or brain or if the patient has a cardiac pace maker.

beside danger that might happen , 
also the resultant image will contain artaifacts that prevents report to be 
accurate or even the radiologist may repeat the scan after removing the cause
Tattoos may also hinder imaging gingand heat up and depending on the ingredients . For the
same reason, eyeshadows (which often contain metal)

Missile inside MRI room

Actually there is no true missiles at all but the environment of the magnetic resonance imaging room can make it possible, when the device is turned on and the powerfull magnetic force starts to work (60000 to 140000 times as powerfull as the earth),when the scan is on, appliances and other magnetic materials may become high-speed projectiles .Materials that are dangerous include oxygen bottles, stretchers, and wheelchairs made of magnetic materials.
My friend Lazo had an accident when he was inside the MRI room and the device was turned on by mistake for few seconds(2-4 s) , his mobile was inside his  pocket & Lazo got pulled toward the magnet with a horrible power till the magnet is off ,
Fortuntly nothing happened to him ,so be carefull of MRI.

mini ultrasound

I was shocked when I saw something like that , but it's real .
this is a portable ultrasound that you can take any where and any time,I cant say any thing more because the image beside is more significant

you can download the pdf (clickhere)from Siemens medical website

Laptop as an Ultrasound device

while I was browsing the internet I found an amazing ultrasound probe that can be connected to a laptop and then you have a fully functional ultrasound device,

Visualization of an Insect Bite on a Bone Scan

From the Department of Nuclear Medicine, Saint-John’s General Hospital, Brugge, Belgium.
Frank De Geeter, MD, PhD.


A 48-year-old woman underwent bone scintigraphy for the assessment of possible trochanteric bursitis on the left side. Whole-body images taken 3 hours after injection of 20 mCi (740 MBq) of Tc-99m-oxidronate are unremarkable except for a rounded area of slightly increased activity at the back of the right thigh (arrow). The gray scale has been adjusted to enhance this area.

 lateral spot view locates the increased activity superficially to the back of the right thigh. On physical examination, a large (10-cm) circular zone of redness was present in this area. The patient remembered having been bitten or stung by an insect, probably a horsefly, while sitting
in her backyard on the evening before the bone scan.
Many insect bites, including those of horseflies (also known as tabanids), are known to cause inflammatory skin lesions, not so much as a result of the physical injury of the bite, but mainly as a result of irritant substances concentrated in insect saliva such as anticoagulants, enzymes, agglutinins, and mucopolysaccharides. The inflammatory reaction often subsides within a few hours but may be followed by a delayed skin reaction. False-positive F-18 fluorodeoxyglucose positron emission tomography resulting from a bee sting has been described.

Thanks for sharing,
See you.

Fasting before PET scan

This PET was acquired from a male patient suffering from a metastatic disease ,
The first (Upper row) was taken after breakfast but he told the invistigator that he was fasting,
PET scan showed minor tumor activity in mediastinal area while CT showed large masses,
Four days later PET was performed again (the patient was fasting that time) which showed the realistic tumor metabolism and multiple metastasis in lung , liver ......(click the image for larger view).
