“…They also showed that the use of a 3.0 T scanner improved surgical planning of sellar lesions (74). Lee et al evaluated the technique of simultaneous acquisition of contrast-enhanced coronal and sagittal images on a 3.0 T MRI and found a detection rate of more than 92% for microadenomas in the pituitary region (75). In comparison, the detection rate was only 82% for uniplanar coronal and 75% for uniplanar sagittal projections (75).…”

The multiplanar combination of sagittal and coronal projections in gadolinium-enhanced MRI are now the preferred tools for visualization and is considered the modality of choice for pituitary imaging (71, 72).…”

Thyrotropin (TSH)-secreting adenomas (TSHomas) are the rarest form of pituitary adenomas, and most endocrinologists will see few cases in a lifetime, if any. In most cases, the diagnostic approach is complicated and cases may be referred after being presented as a syndrome of inappropriate TSH secretion or as a pituitary mass. This review aims to cover the past, present and possible future diagnostic approaches to TSHomas, including different clinical presentations, laboratory assessment and imaging advances. The differential diagnoses will be discussed, as well as possible coexisting disorders. By evaluating the existing reports and reviews describing this rare condition, this review aims to present a clinically practical suggestion on the diagnosic workup for TSHomas, Major advances and scientific breakthroughs in the imaging area in recent years, facilitating diagnosis of TSHomas, support the belief that future progress within the imaging field will play an important role in providing methods for a more efficient diagnosis of this rare condition.

“…7 Imaging is usually performed in a coronal plane, but sensitivity is increased by employing a combination of sagittal and coronal planes. 8,9 Conventional T1 W and T2 W SE sequences in combination with DCE T1 W detect the microadenoma in approximately 70% of cases and improve on sensitivity in comparison with conventional MRI alone. 10,11 Limitations of DCE scanning include difficulty in distinguishing between a simple cyst and a microadenoma as well as the non-standardised dynamic image acquisition time frame.…”

A case of a 50-year-old woman who was referred for the evaluation of possible ACTH-dependent Cushing's syndrome (CS) is described. The localisation of ACTH-dependent CS remains difficult despite many advances in diagnostic approaches. No single test can accurately determine the location of ACTH excess and therefore a combination of non-invasive imaging, stimulation and suppression tests are advised. The recent advances, current utility and pitfalls of each of these tests are reviewed. If non-invasive tests fail to confidently localise the source of ACTH excess, inferior petrosal sinus sampling (IPSS) should follow. Recent advances improving the diagnostic accuracy of IPSS, such as DDAVP stimulation and simultaneous sampling for prolactin is discussed. Where ectopic ACTH production is suspected, newer nuclear medicine techniques, such as somatostatin receptor imaging that recently became available in South Africa, can be utilised. The role of nuclear medicine imaging in identifying ectopic ACTH production is discussed briefly.

“…4 MR imaging with or without contrast agent is most commonly used for this purpose, and dynamic contrast-enhanced techniques are sometimes applied for better tumor visualization. 5,6 Moreover, the magnetic field strength typically applied in MR imaging has recently increased from 1.5T to 3T, and clearer imaging of microadenomas has thus been anticipated. 4 Such effort, however, often fails to correctly depict the microadenoma, and other modalities such as methionine positron-emission tomography have been suggested to meet this need.…”

BACKGROUND AND PURPOSE:Although resection of a tumor by trans-sphenoidal surgery is considered the criterion standard for successful surgical treatment of functional pituitary microadenoma, MR imaging occasionally fails to visualize and identify the tumor and supplementary imaging modalities are necessary. We tested the possibility of dynamic contrast-enhanced multisection CT of the pituitary gland accompanying image reconstruction of contrast agent dynamics to identify the localizations of microadenomas and compared the diagnostic performance with conventional pituitary-targeted MR imaging.
