A CT scan in which the adrenal glands are shown as the triangular-shaped organs on top of the kidneys

An EEG may be used to exclude epilepsy, and a CT scan of the head to exclude brain lesions.

A CT scan of the head is usually performed first when the subject is symptomatic.

More recently, seismologists have been able to create detailed images of wave speeds inside the earth in the same way a doctor images a body in a CT scan.

This low dose of radioiodine is typically tolerated by individuals otherwise allergic to iodine ( such as those unable to tolerate contrast mediums containing larger doses of iodine such as used in CT scan, intravenous pyelogram ( IVP ), and similar imaging diagnostic procedures ).

A CT scan in which the kidneys are shown

Lung cancer may be seen on chest radiograph and computed tomography ( CT scan ).

Once LEMS is diagnosed, investigations such as a CT scan of the chest are usually performed to identify any possible underlying lung tumors.

While CT of the lungs is usually adequate, a positron emission tomography ( PET ) scan of the body may also be performed to search for an occult tumour, particularly of the lung.

In modern scanners, three dimensional imaging is often accomplished with the aid of a CT X-ray scan performed on the patient during the same session, in the same machine.

Also, FDOPA PET / CT, in centers which offer it, has proven to be a more sensitive alternative to finding, and also localizing pheochromocytoma than the MIBG scan.

Abdominal CT scan of an adult with autosomal dominant polycystic kidney disease.

A 2007 review recommends an electroencephalogram and brain imaging with CT scan or MRI scan in the work-up.

Hospital acquired acute sinusitis can be confirmed by performing a CT scan of the sinuses.

A CT scan is recommended, but this alone is insufficient to confirm the diagnosis.

Nasal endoscopy, a CT scan, and clinical symptoms are all used to make a positive diagnosis.

This includes a CT scan or an MRI of the brain, ultrasound of the neck, an echocardiogram of the heart.

From the symptoms and signs, it may be very difficult to distinguish acute transverse myelitis from these conditions and it is almost invariably necessary to perform an emergency magnetic resonance imaging ( MRI ) scan or computerised tomographic ( CT ) myelogram.

CT scan often is not helpful, as cerebral abscess is uncommon.

Lumbar puncture procedure is performed only after the possibility of prominent brain swelling is excluded by a CT scan examination.

* MR & CT scan diagnosis of HSV encephalitis Medical Image Database

However, in cases with slight symptoms, a faster and cheaper CT scan ( although it is inferior to MRI scan ) may be recommended.

While a CT scan can show the bony structures in more detail, an MRI scan can better portray soft tissue.

The diagnosis of these complication can be assisted by noting local tenderness and dull pain, and can be confirmed by CT and nuclear isotope scanning.

The diagnosis is confirmed with a spinal CT, myelogram or MRI of the spinal cord.

The diagnosis can be confirmed by ultrasound and / or CT.

The diagnosis may be confirmed by CT, MRI, or ultrasonography.

The diagnosis may be suspected with chest X-ray and CT scan, but must be confirmed pathologically, either with serous effusion cytology or with a biopsy ( removing a sample of the suspicious tissue ) and microscopic examination.

The diagnosis is generally confirmed with a CT scan of the head, or occasionally by lumbar puncture.

The diagnosis is generally confirmed with a CT scan of the head, or occasionally by lumbar puncture.

Diagnosis is usually confirmed by an MRI scan or CT scan, depending on availability.

At Mayo Clinic, FAMMM patients with a confirmed mutation and family history of pancreatic cancer are offered screening with either high-resolution pancreatic protocol CT, MRI, or endoscopic ultrasound starting at age 50 or 10 years younger than the earliest family member with pancreas cancer.

The diagnosis of Boerhaave's syndrome is suggested on the plain chest radiography and confirmed by chest CT scan.

Outside of the Finnish study, a separate study also confirmed that the CT SNP at-14kb is an indicator of lactase persistence, with the exception of two individuals.

Physicians and researchers can use additional laboratory assessments, such as bioimpedance, MRI, or CT, to build on the findings of a clinical assessment ( physical evaluation ).

The increased iron stores in the organs involved, especially in the liver and pancreas, result in characteristic findings on unenhanced CT and a decreased signal intensity in MRI scans.

Diagnosis is based on these clinical findings in combination with laboratory tests ( such as the D-dimer test ) and imaging studies, usually CT pulmonary angiography.

Through thorough clinical evaluation, via physical findings, detailed patient history, and advanced imaging techniques, such as angiogram, computerized tomography ( CT scan ), magnetic resonance imaging ( MRI ), or more rarely transillumination ( shining of bright light through the skull ) after birth are the most accurate diagnostic techniques.

It is important to optimize the parameters of the CT examination, because the underlying liver disease that most HCC patients have can make the findings more difficult to appreciate.

The reported sensitivity and specificity of CT scan findings are in the range of 90 – 95 %.

If the CT scan is negative but a ruptured aneurysm is still suspected based on clinical findings, a lumbar puncture can be performed to detect blood in the cerebrospinal fluid.

The diagnosis of bronchiectasis is based on the review of clinical history and characteristic patterns in high-resolution CT scan findings.

In one small study, CT findings of bronchiectasis and multiple small nodules were reported to have a sensitivity of 80 %, specificity of 87 %, and accuracy of 80 % for the detection of bronchiectasis.

These findings, taken from the history and physical examination of the patient ( along with the anatomic demonstration of stenosis with an MRI or CT scan ), establish the diagnosis.

37 % of patients receiving whole-body CT scan may have abnormal findings that need further evaluation.

* eMedicine Radiology ©-pictures of X-ray, CT scan, and MRI of various findings of TB disease:

CT abdomen should not be performed before the 1st 12 hours of onset of symptoms as early CT (< 12 h ) may result in equivocal or normal findings.

In addition to tests corresponding to the above findings ( such as EMG for neuropathy or CT scan and bone marrow biopsy for myeloma ), two other tests give abnormal results.

The most characteristic imaging findings are usually obtained with CT.

Video-assisted thoracoscopic biopsy is the most definitive and widely used technique, but transbronchial biopsy can also be effective In some cases, the diagnosis of LAM can be made with confidence on clinical grounds ( without biopsy ) in patients with typical cystic changes on high resolution CT scanning of the lung and findings of tuberous sclerosis, angiomyolipoma or chylothorax

If esophageal perforation is suspected, even in the absence of physical findings, contrast radiographic studies of the esophagus and a CT scan should be obtained promptly.
