Positron emission tomography - computed tomography (better known by its acronym PET-CT or PET/CT) is a medical imaging device which combines in a single gantry system both a Positron Emission Tomography (PET) and an x-ray Computed Tomography, so that images acquired from both devices can be taken sequentially, in the same session from the patient and combined into a single superposed (co-registered) image. Thus, functional imaging obtained by PET, which depicts the spatial distribution of metabolic or biochemical activity in the body can be more precisely aligned or correlated with anatomic imaging obtained by CT scanning. Two- and three-dimensional image reconstruction may be rendered as a function of a common software and control system.
PET-CT has revolutionized many fields of medical diagnosis, by adding precision of anatomic localization to functional imaging, which was previously lacking from pure PET imaging. For example, in oncology, surgical planning, radiation therapy and cancer staging have been changing rapidly under the influence of PET-CT availability, to the extent that many diagnostic imaging procedures and centers have been gradually abandoning conventional PET devices and substituting them by PET-CTs. Although the combined/hybrid device is considerably more expensive, it has the advantage of providing both functions as stand-alone examinations, being, in fact, two devices in one.
A pet is a household animal kept for companionship and a person's enjoyment, as opposed to livestock, laboratory animals, working animals and sport animals which are kept for economic reasons. The most popular pets are noted for their attractive appearances and their loyal or playful personalities. Their pedegree may also be a factor.
In some cases pets may also provide their owners with benefits, such as providing companionship to elderly adults who do not have adequate social interaction with other people. While some people believe in the physical and emotional benefits of owning a pet, scientists are currently working to verify these ideas with medical studies. There is now a medically-approved class of "therapy animals," mostly dogs, that are brought to visit confined humans. Pet therapy utilizes trained animals and handlers to achieve specific physical, social, cognitive, and emotional goals with patients. Walking a dog can provide both the owner and the dog with exercise, fresh air, and social interaction.
A hundred miles and running, niggers going at the end
of me
Niggers switching sides, give me nothing like it’s the
end of me.
Niggers having family, but I know these niggers into
Pown me, thug it to the motherfucker sin is me.
Imma train the topic time down, bitch, I’m riding in a
‘rarri.
If you don’t like me, than I’m sorry.
I ain’t og, I’m just being me, fucking pretty clear.
I rap about this shit, ‘cause I did it.
Life don’t change, neither do the game,
Niggers getting money, but the rules stay the same.
Who I’m gonna sound with, who I wanna ground with?
That’s my only question, nigger, see ‘em G I’m down
with.
Cocaine mirrors, cold money guns, every nigger I fuck
with with the g I make them bun,
So I never leave the house without my chain on my gut,
Got on my old boy Gucci so I fresh pearl once.
See, nigger, see, I feel like I wanna release, nigger,
I got to face earth, you know what I mean?
And then I got nothing to do and get no money
And that, nigger, that be a hundred.
That be a hundred with yourself, that be a hundred with
the niggers,
A hundred with you, you know what I mean?
Man, I got a lot of young nigger around me, nigger,
And that’s straight of low life family, nigger, could
kill for each other,
That thing is real.
Murder was the case, nigger, jump a hoardal with a race
nigger, down
Then I put it in your face, to the face, on my case,
nigger,
Told my lawyer go to trial, I’m doing it big in the
meanwhile.
If I lose, place a riot for me, if I die don’t stay
fire for me,
Pour on some liquor and get higher for me,
I’m doing this thing for my home boys,
I have it, oh, lord, so surely can avoid.
I came here speaking from my heart for some time around
Am I a real rapper or just a nigger on lands?
I don’t know, I’m confused, do I suppose to be rich?
You know that hoe ain’t your hoe, she’s your supposed
to be bitch.
No supposed to be clip, I want no allias,
You see ‘em G, homie and we don’t franchise.
I get green gas off the whipe ass, don’t get in that
And he get bout time.
Hallelujah, bless my shooters, serve my jazle, watch
him hit that shooter.
Fuck that rap shit, I don’t fit in,
How they fuck boys, how they fake friends.
Streets on fire, plug on gold mode, streets so damn
dry, I might get a truck load.
Fuck your country, I won’t sign it, labels keep calling
